You can approach a counsellor for any reason - but maybe say more about concerns re low self esteem/anxiety/difficulties relating to others then discuss specifics when there.
I have suggested it here way back but I’ve started using Gemini, AI for random stuff - there’s also ChatGPT and Claude - probably others. If you tell them your issue they assist - from drafting an email to partner arguments to what to wear - it’s not infallible and it’s a bit of a cheerleader as it gets to know you but it can be helpful - and is free.
For goodness sake though please, please be aware of toxic offers to support guys on the ‘net - these would also make it harder to get a date in the end - women despise this type of masculinity that is sold on some places.
You are still worrying about photos on sites, height, weight etc. Everyone will say something different- re photos there’s usually more of a consensus of what you don’t click on - you’ll find some examples on these threads - holding a huge fish, pics with apparently ex partners but face scrubbed out, bare chested, group pics so who is it etc etc - otherwise a nice smile, looking happy enough (not manic!) is what I look for I think - at least I swipe left at angry/miserable looking photos.
Height/weight is personal too - what is annoying is if it’s a fib - there’s an awful lot of rounding up height - an inch ok but 5 not so much when you meet them - same with rounding weight down. Personally, I do like guys to be taller but I’m only 5’5 so it’s not so hard, just annoying to find my 6ft date was 5’4 I guess lol - honesty all the way.
Attracted to is so individual- nowadays as long as I’m not unattracted to then I’ll give it a shot as 3D and real life is so different anyway so you don’t know how they’ll really appear nor how you’ll feel. This time around Fortunately, both dates looked like their photos - in the past I’ve met massively different appearing guys and it’s not only disconcerting you feel like they lied from the get go so don’t want to bother. I used to like to put on an ok pic but not over flattering so they had a slightly better start - nowadays that is more difficult lol but I definitely never want to see a nasty shock in their eyes haha - so I try to be as realistic with pics as possible and whilst not everyone could or has been attracted to me on the date at least I haven’t sold them a complete dud.
Honesty all the way and don’t keep over analysing so much.
