I don’t know how to deal with embarrassment

Please help. I go to a very small, tight-knit university where everyone’s like family. There was this one party where I got so drunk I passed out in my own vomit in the bathroom and this one guy who’s really kind carried me out of there and called me a cab and brought me home, made sure I got into bed ok and left me water and a bowl to puke into. Nothing ever happened between us. Now while I was passed out and we were waiting for the cab, I was laying in his lap with my face RIGHT ON his crotch and I at this point was literally unconscious so I don’t remember it but his friend took a picture of it. This was in December. I’m now friends with the guy who took the picture and he told me he’d put it on a huge poster and give it to me for my birthday but I’m SO embarrassed this pic exists and I cringe so hard just thinking about that night, I think I’d be so extremely embarrassed and uncomfortable if he actually did give it to me that I wouldn’t want to see anyone at that party ever again. Someone tell me how to stop him from doing it without making it awkward and seeming like a party pooper?
