Receiving female attention, but never acting on it.

My insecurity about my dick size is holding me back. I'm now 20 and still a virgin. I'm insecure about other things as well, but they don't hinder me as much or at all like this does.

Women me give all the signs that they're interested such as flirting, touching, groping, and giving me their numbers. Of course I flirt back as well, but it usually ends there.

Even though they're basically throwing themselves at me I never act on it, because of my size. I've turned down hook ups and blowjobs.

Honestly, I don't think I could deal with possibly being laughed at or mocked cause of my size. However, in past unrelated situations where I experienced embarrassment or shame I just took it to the chest, and kept pushing. Maybe I should do the same here.

I'm not the type to wallow in sadness (especially about something I can't really change) so do you all have any tips for me? Thank you.
