Ungodly Pain During Sex

I want to start by saying it was not my first time. Been with my boyfriend for a year and a half and I have been on antidepressants. I have no sex drive and when I do I can barely get wet. Lately Sex with my boyfriend has been so UNGODLY painful that I just want to cry!😭😭 His package is so much bigger than what I'm used to and has always kind of hurt but it got better the more we did it. I love him so much and find him so sexy but I don't know what to do! I want to enjoy sex again and I feel like the antidepressants are killing it. I'm literally sitting on a bag of ice right now😭 help!!!😭😭😭😭
