am I too old for this?

[Tangofantastic]

Soooo quick history - I’m a single mum of 2, 41 and been seeing a friend / partner for a year or so now. Lovely guy, he has no kids and it’s been a friendship that grew into something more but is limited as I have my ND kids 90% of the time so I only get to see him 2-3 times a week and for a weekend every 8 weeks. (Mix of shift work + my kids).
he’s younger than me by 7 years which probably hits my first insecurity marker🤦‍♀️he’s gorgeous, funny, kind and clever and as conversations happen its clear
he’s had lots of partners before me and is very experienced in bed, I think from
the gen that expects sex to be a bit “exciting” each time, everything shaved etc. no judgement but different to my experience in life so I’ve had my eyes opened in a good way but also I do feel kind of old
sometimes as a result (like, erm what’s up with “boring” missionary and not shaving?!)
anyway fast forward and the last couple of weeks he’s been under some
work stress and every time we meet up and we have sex he can’t Cum- we’ve tried each and every way and…nothing! He’s blasé about it saying it’s just his stress, he can’t even make himself cum when he’s on his own which led to a slightly off tangent chat about how he masturbates Every day and surprise that I seemed taken aback by that, pointing out that if he only gets to see me 1-2 or 3 times a week of course he’ll do that on other days and don’t I? And I had to stop myself saying are
you kidding? The nights I’m not with you I’m in bed by 10 With motherland and asleep by 11😂
is this the younger gen? I feel weirdly old and self conscious after these chats and I can’t work out if I am or if he’s got
an Above average amount of experience and therefore expectation/
drive? starting to wonder if this is really
compatible in the bedroom sense long term 😵‍💫

It's not "the younger gen", it's just normal human variation.

He's got a high sex drive. That's fine. Maybe he does have more experience and/or more "variation" in his past. As long as he's honest and meeting your requirements for sex, companionship, monogamy or whatever else you need within your relationship, that's also fine.

You have a different sex drive, and your own sexual preferences. That's all fine too.

He takes care of his needs, and he seems comfortable with his body and its reactions (i.e. not stressed nor embarrassed about not orgasming because he knows it's perfectly normal for stress to affect responses).

I mean this in the kindest possible way, but from my reading, you've not mentioned anything he's done or said that indicates it's a problem other than in your own head, so maybe just try to stop overthinking it and enjoy?

If the sex isn't doing it for you, and it sounds like something is blocking him it might not be worth pursuing.

I think seeing someone 2-3 times a week is just fine. For many people, that would be considered quite a lot.

If you really like him and enjoy his company, try to accept the relationship for what it is and don't look for anything more, eg a commtment.

I have the feeling from what you say that he could be a sex pest. You don't have to 'cum' all the time to be a sex pest, plenty of people aren't bothered by that but still crave sex, being on the edge, etc. That may be OK for an affair but would you really want someone like that on a permanent basis?

Keep it light and keep your options open, there are more fish in the sea. If you can't, end it.
