Sex anxiety or erotophobia

Hi!

One of my major insecurities is low number of sexual partners.
It just makes me feel incapable of doing anything and usually I lie the count to be bigger than it is, cause in case I get in bed with someone I can just blame them for bad sex or usually just get wasted.

But usually when someone approaches me in a sexual way I get this feeling of anxiety that I have no idea what I'm doing and since I'm a guy it's rather a major concern. Usually leading to a situation where I rabbit out with an excuse, cause I don't want to get embarrassed.

Also the high performance stress that spikes in usually makes me incapable of enjoying sex yet the amount that I desire it just grows by year by year. Actually I just grave it so much today that I might flirt to random strangers and touch of other people, but yet usually this leads to other people find this creepy or rabbit out by themselves and if it leads to sexual stuff I usually again rabbit out at the last moment.

I think I've done the rabbit thing now over 10 times ( like pass out or just I can't do this or ). Also have commitment issues cause I strongly belief that if other people knew how screwed up I am they'd leave me on the spot so I rather just not get too close with anyone.

I've thought of using sex worker services, but I'm not sure would that make my self-esteem even more worse since I could rabbit out even with them so I thought I'm going to go with the traditional way. But it's rather hard since I'm already 26 and only had like sex three times where I kinda dissociated from it and saw it as a mechanical performance and yes I have never had an orgasm.

Thanks.
Feel a lot better even by now.
