But let's see if there is a flip side to this type of arrangement.
Having sex for a woman causes an emotional bond, unlike a male for whom sex is just a physical activity. Are you going to be ok with this bond growing stronger the more you have sex with this guy. Can you handle him using you as a sex toy without being emotionally involved with you.
Friends with benefits is a great deal for a guy but is it a great deal for you?
Think about it before you jump in with both feet....
