Hi
I've been in an on off relationship for two years. We recently broke up for two weeks, but I have always suspected he was cheating. We had\ have a fantastic sex life. I say have because we kissed and made up yesterday.

My question is normally we have very long intense sex..... Lasting a few hours at a time and sometimes 4-5 times in one day.

When ever we have been apart like recently, when we have sex he climaxes in 2mins and is so full of sticky thick semen. Does this mean he truly has been faithful in our time apart.

The mean fact the he climaxed so fast and was totally exhausted afterwards??
