Looking for some insight on this..

To preface this i am a 23 year old guy who has not been in any relationships with guys before. This has been the first year that I have been comfortable with my sexually and I have finally opened up enough to start dating guys. I am still not out, but I have been trying to expierence dating men and reach the point where I can come out. Anyway, the problem that I have run into may seem weird but I want to know if I am over exaggerating or not. I have been a a few dates and have hooked up with a few guys and many of them really like calling me thier "bitch". I know that it sounds funny, but I find it pretty disrespectful and it turns me off alittle. I just Wana know if anyone else has felt this way or even has this happen to them. Any insite would be awesome.
