I haven't had sex or actually don't anything with a girl because of cumming too fast. If I cum fast during masturbation will I last longer during sex or getting a bj? I have heard of people lasting longer during blowjobs but I didn't know if it was true
From my experience, when I give my boyfriend a blowjob he lasts longer. When he's inside me, he cums A LOT quicker.
I think it depends if you use lube when you masturbate or if you do it dry. If you do it dry then you will probably last longer when you actually have sex because there is a lot less friction. You can also put on a condom and add even more lube to decrease the friction more - that should help.
Also - masturbating shortly before you have sex will decrease your sensitivity!
