To think this is not professional or am I overacting? Sex talk.

I don’t see any sex talk there at all.🤔.

The women in my office malr jokes about oral sex and wanted to organise a trip to the Dreamboys!

It makes me cringe but I am the only one who doesn't join in so I let them get on with it, the manager joins in too so no point complaining!

1 - once the senior asked to work for a few weeks abroad in a sunny place known for vacations and the HoS said: ‘yes but I don’t want to see any naked men walking around while on online meetings’
2- in a meeting with a solicitor who is outsourced and not part of the team to discuss an important issue, the senior asked the solicitor in a notmal way to have a doc as soon as he could deliver and the HoS said: ‘stop flirting and using your charms, it does not work with lawyers
3- HoS was talking about how she enjoyed a day off with her husband and then complained of back pain, then the senior insinuated that her and her husband had too much sex

I can't imagine anyone considering No.1 to be 'sex talk'. It's an incredibly mild joke about working in a holiday destination. How can you possibly find that offensive?

No.2 isn't about sex at all. Again, it's a mild joke.

No.3 is moderately inappropriate but if the HoS and the senior are friends and know each other well, it's really not that bad. Certainly nothing I'd even remember after the meeting, to be honest.

For context, I used to work in office where a colleague came into work one morning and announced that he'd fingered some random woman while they were queuing for drinks at a bar the previous night. Now that is the kind of thing I'd call inappropriate 'sex talk', not the sort of things you've listed.

I work in a traditionally male dominated environment. That kind of talk by either sex never happens. If it ever did, it was drummed out of the workplace before I started 25 years ago. Yes, it’s a very uptight environment, but they are extremely careful about making sure the women who have joined the workforce feel welcome.

I don't know why you guess this is about professional jealousy
Surely it's that a lot of people, including OP, expect a standard of professionalism at work and not juvenile inappropriate banter.

Having recently refreshed our sexual harassment in the workplace training,, this could be classed as harassment. It doesn't matter if not directed at you , it is in your presence and discussed in front of you and you feel uncomfortable .
They as senior managers and heads of service should know this.
It is very tame in the scheme of things mind you . I would find it extremely cringe and embarrassing that they behave like this to be honest but probably not raise it myself though you would be entitled to do so. To me it's just embarrassing rather than offensive.
They however should be aware of their audience, even if cringe banter is accepted amongst their close group it is embarrassing to do in front of others and could be classed as harassment.

I work in a huge team that include traditionally male workforce and have heard a lot worse ro be honest and not a lot phases me now.

I would hazard a guess that the actual problem stems from you being junior to younger colleagues, and thinking you should be a more senior position as you are more serious and therefore more “professional”.

It's sexual harassment.

You're being exposed to talk about sex that you're not comfortable with.

And yes it's really unprofessional. It's not any less unprofessional, or any less sexual harassment just because someone on Mumsnet thinks it's fine to show her colleagues dick pics off tinder, so therefore you must be overreacting.

Sounds a bit on the "Carry On" side. I think you are all just very different people. They obviously think these comments are hilariously funny, but its grating for you to keep listening to it.
At least they must realise you are not responding to it, with the wink and nudge they are expecting.
What do the other colleagues think of it?

you don’t fit in. Perhaps there is another team that would suit you better.

This happened in an office I was in, it's unprofessional and I don't want to put up with that at work. They were young single women mostly getting a bit carried away. I moved offices and it's not an issue in the new office.

I'd probably find it more icky if it was more senior people as I'd expect them to have grown out of it

I’d think they were a bit thick and I would tell them I found it inappropriate , the bits I did I mean not an overall you are inappropriate but would do it in the moment not after. Doesn’t mean they have to agree but by using “I” statements you aren’t saying they should. But I’m 52 and probably wouldn’t have done when I was younger. Some people join in because they are people pleasers or are embarrassed not to so don’t be surprised if you are not the only one who doesn’t like it.

its also sexual harassment if you read the act.

It's really tame

When the woman in my workplace used to say

"I wouldn't kick him out of bed, I'd ride him till the cows came home. Reverse cowboy is my best postion"

We all used to roll her eyes. She was about 60 and she would be talking about the 20 year old delivery guy.

I'm so disappointed that it's all so tame!

I was expecting something like this -

A lot of people don't want to talk about sex at work though. Many people see the workplace as a professional place.

I remember everyone used to cringe at the one woman in out workplace who used to talk about sex a lot

Good heavens! I think you’d actually die of embarrassment in my workplace then. None of that actually sounded very bad at all.

If you aren’t comfortable with it then you should raise it. No one should feel uncomfortable in the workplace, but that said no one was whipping out any dick pics they’d got sent on tinder (this has happened in my place of work).

It all sounds quite tame and just work friends having a joke together. I think that’s the difference, maybe they see each other as friends as well as colleagues, and not just colleagues.

I thought you were going to say that they came in to work each morning and discussed their sex lives, conquests from the night before, who they'd like to sh*g in the office etc (which would be inappropriate)
The things they say are a bit cringey but i think you are being oversensitive OP.

I wouldn't like it either. In one workplace I was in, none of the women talked about sex, except one older woman. She was always making crude comments about sex.

I remember one woman blushing and looking uncomfortable and the older woman said "what are you blushing for, you're a married woman!"

I don't think it's appropriate to talk about sex at work. It makes people uncomfortable

They sound very immature and childish.
And unprofessional.
It would annoy me and I'd be tempted to tell them to grow up.

I have a new manager who is so painstakingly professional it’s boring as hell! All face aching smiles and hi how are you and dull small talk. I’ve had some real laughs and lots of banter in some of my previous roles and I really
really miss it. It’s used to make the day go faster and a bit of humour helps so much. No way you can do it now as people feel the need to control every interaction around them.

In my experience the people talking about the sex are the ones that aren't having the sex. I'd find this weird too OP.
