Hurry! pit, help me, i might be getting laid for the first time today!

The woman is inviting me over and her parents are gone. (hooray)

Okay. so my question is: how many hours should i jack off beforehand so i'll last atleast 10 minutes or so?

I already wanked last night, but I usually whack off 2-3 times a day.

Help me out here, pit, i don't want to be embarrassed.
You should wait till both of you have your clothes off then wank.

Take it to the sex thread.
You don't need to jack off before.
I don't want to boast or something, but I don't. Lasting 8 minutes is long enough!
