Depends on what you mean by "nice." sometimes "nice" is a euphamism for fantastically annoying. I don't want a puppy dog that follows me and agrees with everything I say and do, and never challenges me on anything. Been there, had that, and it bored me to tears. "nice" can mean so many things. I like actual nice men..but most that actually first and foremost identify themselves as a "nice" guy are mostly just obnoxious men who need to have something to explain why they can't keep a decent chick. oh yeah, im "nice" and women don't like that
as for booty calls..not every relationship needs to be an Im going to marry you because you are my souuulllllmmmaaatttteeee type deal. However I am too proud and too attached to my junk being healthy to want any kind of relationship with someone who is sleeping with other people. that's it. I don't really see anything wrong, if two people are on the same page and enjoy each other, why they can't sleep together and not consider themselves in line for the alter. but it's gotta be exclusive, sorry. I have watched friends sleep with guys who never call them or talk to them again, and its pathetic. I never put myself in that position. I've never had it happen to me...It could be because I am sooo fantastic they all want to marry me
but more likely it is because I am not stupid and some guy that has rarely talked to me all the sudden wants to get busy just isn't getting any. I wish more moms would teach their daughters this crap.
my mom used to tell me "when devoid of any options, goat herders in the desert would screw a goat. If they would screw a goat, why the hell do girls feel like they are special? they are just that night's goat" best advice ever. So many girls think because a man will sleep with them, it means they love them. THATS what causes the confusion in these casual relationships, stupid girls (and sometimes guys) who believe they have won some kind of war by getting into someone's pants.
