Search Results: sex more fun

I have a friend who knows a guy who went away out of his home state/city on business for a long time, like a whole year, and he couldn't go back home at all-- didn't see his girlfriend for a whole year. During that time, his girlfriend told him that as soon as he got back, she expected a ring; not even wanted, but *expected.* She also expected him to not touch or kiss or get physical with any other female for that whole year, and got angry when he apparently kissed one other girl one time, or something. They ended up breaking up later; I don't think he was feeling it any more because he was sick of being told what to do, and a whole year is not an okay amount of time to be without sex or any physical romance whatsoever.

The point is, his girlfriend at the time was not particularly pretty/attractive. This is something I've noticed with other people I know as well-- the expectations, the self-righteous overblown anger at something that a reasonable person shouldn't get mad over, etc. I've never noticed this from people who are objectively attractive, though to be fair it's possible I simply haven't been paying as much attention, but it seems to me that they're more likely to say like "oh my girlfriend is talking to other dudes at a bar? So what? Let her have fun." I almost never have my less-attractive friends (especially the female ones) say stuff like that.
Is this something anyone else notices? Are less-attractive people more likely to be emotionally insecure? Or does it not matter one way or the other?
