i've been having trouble with regular sized condoms, or i hope its the condom... everytime i put one on i lose my hard on either immediately or a little bit into intercourse ('m straight btw). the thing is when i'm receiving either a handjob, blowjob, or just jacking off, i have never lost an erection. is it possible that i just need to buy a larger condom? or do i have some sort of physical/mental issue i need to work out? edit: i'm 18 years old.
