I especially like receiving comments from women too, but it's not mostly because I'm straight...I'm not laying pipe to anyone here. I just think, considering all the attention (some of it pretty sketchy) the women here get, it's nice when they give some of their own. A lot of the times I feel some the men on here compete to be slutty to get attention, which makes the comments from the women (on average) seem more genuine. Just my two cents.
edit: not to say I don't appreciate the comments from the guys who don't proposition every dude on the site...those are great too.
