Unfortunately it is not confined to this forum, most of the world is clueless, they are just better at hiding it than those here. LOL
If you are talking about how long it takes a guy to get off then you are wrong. My ex bf takes about 3 -5 minutes to get off from vaginal sex for the whole year and a half that I was having sex with him.
The first time i had sex was really disappointing but when I tried to had sex with MILF it was really unforgettable.
Whether she's had sex before or not, I give the marriage no more than 6 months. If she's smart, the sooner the better.
