@WorryingNotSleeping I'm sorry to hear you're feeling like this. Perhaps I can give a little perspective from 'the other side'.
I've recently started a new relationship (I'm female, he's male), and it quickly became apparent that he, as well as inexperience (despite being quite a bit older than you) has difficulties with physical intimacy.
I initially felt quite rejected and unattractive but he explained a little about this to me and I did some research to try and understand more. I've now completely changed my expectations/approach and we're taking things v slowly and at a pace that he's comfortable with. As a result of me understanding more he has relaxed more and it is actually really lovely taking things slowly - he's now relaxed about kissing and so we're doing lots of that
.
A few things that helped: we were good friends first and therefore there was a level of existing trust on his part/willingness to put in effort on my part (OLD had never worked for him in the past for similar reasons to you), seeing each other frequently for short periods of time in 'safe/comfortable' for him locations so there isn't the 'pressure' of an organised 'date' with perhaps 'expectations', me understanding that his reluctance isn't a reflection on how he feels about me (that was an important one for me), starting slowly with 'non sexual' but sensual touch - eg holding hands, stroking arm, cuddling, so he became comfortable with close physical contact - kissing then flowed naturally from that.
I would gently suggest that you would be better off looking at opportunities to develop friendships/get to know men first rather than OLD. While you may get lucky and find someone who is willing to be patient & understanding and who you find attractive I think so many men on OLD have a 'sweetie shop' mentality and just move on if anything involves much effort. Being honest I'm not sure I would have been willing to put in the effort/patience with my boyfriend if I'd met him through OLD and hadn't known him well and had the friendship already.
I also think that it's important to be at the stage of feeling comfortable about communicating your need to take things slowly before you get to the point of it being expected that you will kiss - as the 'more experienced' partner I needed to understand that in order for me to adapt my expectations/approach and also so I understood that it wasn't me being rejected/unattractive etc.
My boyfriend worries sometimes that he's 'hard work'/a lot to deal with/not worth it etc but I don't feel that at all. I know he is a wonderful, kind, caring man and I'm enjoying our slow process of discovery together and seeing him relax and start to enjoy physical closeness is rewarding and bringing us closer emotionally as well if that makes sense.
I hope that you are able to find a decent man who can also help you to relax and enjoy intimacy. Good luck
