This is an issue ive been having with a couple of hookups, but not all. sometimes ill be in the right position, angled the dick just right and I can't seem to find the hole. Ive tried a few positions and can only barely get it in sometimes. Then when it is in, I start going and it slips out, rinse and repeat. For context I'm a man hooking up with men, so this is exclusively anal sex, any tips on how to find the hole and stay in it?
Edit: it's 6 inches and curved to the left, if that guides anyone to a solution
