In full disclosure—as someone who frequently comments on photos (always in a positive way) I will first look at the profile of the male and if he is seeking a female partner, I will be very careful not to write anything of an erotic nature, but simply compliment his bellybuilding success. If he lists seeking a male partner then I will comment on how sexy his new pounds look. I’ll also be more specific if he’s listed himself as seeking women, but has PMed me thanking me for the compliments and has responded in a more erotic manner.
That makes you a rare occurance on this site, most people just message/comment without so much as a look at the Profile page/I-Seek-You. This seems to be the most parsimonious answer to me. Sort of curtailing the unwanted attention *or at least trying* by posting their interests in the same place they're posting their images.
Though yeah...if you're secure in your sexuality it really shouldn't matter either way. I myself take my comments as they're written, if they're positive they're taken that way and vice-versa.
