I'm about to make some sites with (allegedly ) straight guys. I've used the word "straight" for my site titles too many times.

So I'm wondering whether the word "breeder" is an offensive or perfectly normal term for a heterosexual man? I think I've come across collocations such as "hot breeder cum" more than a few times. If the term is derogatory in the same way "fag" is, I'll avoid it at all costs. But for now I just don't know.

English isn't my mother tongue.. that's the reason I'm asking.
