Enough stamina for hours
I am a very pensive, philosophical guy, but when it comes to the bedroom I am extremely passionate. I have plenty of experience even at my young age to know what women like. I tend to be very selfless in all walks of life. Also, I am addicted to sex and will do everything in my power to make a woman scream every time.
On the other hand, the most important thing I look for in a woman is a sense of humor and intelligence. If I can't sit down and have an intellectual conversation with her, then it's probably not worth it. Sex is much better with someone to whom you are mentally attached somehow.
