i met up with this asian chick from tinder last night at her place. I hadn't had sex in like two weeks so i went over to her place and came within like 5 min without being able to stay stiff for second round.

I am 20yrs old and stopped masturbating for the last month and im wondering if this is the cause of it since i think im still too young to be getting E dyfunction and i was able to go no problem a couple weeks ago...

If that's the case, how do ya'll work on not coming too quick or managing to keep the hard on without having to masturbate before hand?
