Sexy Friends...The new double standard

Question… Why are men thrown off by women that just want to be sexy friends and nothing more? This question comes from one of my loyal readers and she brings up an interesting point. For a long time men have been ok with just being sexy friends with women (for clarification, a sexy friend is a person that you have great ‘no strings attached’ sex with #thatisall). In these sexy friend scenarios if the guy wanted to talk, or go out, or do other dating like things (in addition to the sex) they could call on their sexy friend and she’d usually oblige. Typically in these situations if the woman started to “catch feelings” the guy would quickly remind her that they are just sexy friends. Well it seems that these days more women are opting for the no strings options with men, but some men aren’t as good as handling being treated this way by women. Now from my very unofficial process of consensus building (i.e. talking to a few of my friends) for a woman there are a couple of rules to sexy friends and they are at follows 1) we are not real friends, we are simply two people that like having sex with each other. 2) talking (unless its related to the details of when/where/how the sex will talk place) isn’t really necessary. 3) both parties should wake up in their own beds…there is no need for any dating like behavior b/c that just makes things too sticky. 4) when the sexy friend situation has run its course let’s just move on, no need to discuss anything. However, when such rules are implemented by the women some men can be a bit taken aback by it. It can sometimes come as a shock that the woman has no interest in participating in any of that extra stuff, she just wants sex. So…Why is it okay for a man to get what he needs out of a sexy friendship, but it seems to be assumed that a woman will be open to more if the guy decides he wants it?
