No. I find it disrespectful. If I don't know someone, I don't even look at them; I look through them.
Being in a relationship, everyone is androgynous, and I find it disrespectful to envision something so crude.
I've had people ask me if they think they're good-looking, and the most you might get out of me is, "By societal standards, many would find you [un]attractive." I don't actually admit to anything, because I don't have anything to admit.
I also don't gossip about who's super hot, or who I'd let have me, or anything like that. I have more respect for myself and others to basically lower them down to something so poor as sex. As humans, we're better than that, and we're worth more than that. If anyone (other than my boyfriend, obviously) saw me and only thought about getting off, I would be thoroughly disgusted. It's not flattering; it makes me less than a person, and I don't care for such disrespect. People need to be more humble.
I recognize sex to be natural. I do judge people who are promiscuous for the same reasons described above: the devaluation of human worth to a purely carnal level. I just think people place too much emphasis on it than is normal, and people can treat others as "lesser" beings because of superficial face-value. I don't wish that upon anyone.
