Yes, I have some experience with this one!
Unfortunately I can relate all too well with "not getting it up" lol
Mainly in my younger party years, mostly due to drugs/drinking.
I've casually dated women who I couldnt get it up for a few times in a row and they still blew my phone up, complimented me, still would say how I turn them on, still brung me food, sent me money ect lol I just take it as them being very into me.
Hell, I've had one night stands were I couldn't get it up and those same women still pursued me after the fact, these where random girls who didn't know me from a can of paint.
You gotta have the swagger to back it up though, as in, act like you don't give a fvck and it's not a big deal.......
OP, if you don't mind me asking, what exactly do you think the reason youre having this issue?
