I am not an obese person, nor have I ever had intercourse with one (not of a sexual kind, at any rate). And that kind of thing certainly isn’t my “kink.”

Aeschines, first I want to say that I have a problem in your post that you kind of insinuate that fat people seem to be unable to have sex without someone having some sort of distrubing world view. Seems pretty shallow on your part, but that’s your cross to bear.
As a fat guy, I’ve had sex with both what people would call heavy and proportional women, and I’ve at least never had a problem getting “the naughty bits” as they say together. Every one of them was a very attaractive woman IMHO, and I’d quantify all as being in the “hot and enjoyable” category as well. My wife is on the heavy side, and about the only thing is that she doesn’t like is not having her breasts supported as some previous posters have mentioned.
Since we’ve had a lot of women post, from a guy’s perspective I can say that the biggest thing is that I worry about is that at least I need to worry about is getting the right angle for penetration due to my weight being lower on my body (and hence in the groin area). I know I have sometimes felt bad about having to take a few seconds to get everything matched up (but thats probably just in my head, I don’t think it’s been a problem for my partners). But once it gets worked out properly, it’s all good!
Sure, we haven’t gone through the entire Kama Sutra, but thats mostly because I am not that flexible and I haven’t figure out how the get my body flexible enough to put my legs behind my neck. :eek:
Oh and alice in wonderland I sweat like a pig too durring sex, but I can sweat in a snowstorm, so I know what you are talking about! Keeping a fan on in the room helps a lot 
More to the OP’s post however, I know a couple that are the opposite extremes. The Guy is a workout maniac, sixpack abs, etc and the women is VERY heavy. However they still find each oher attactive, and based on her comments still enjoy a very active (and in fact adventerous) sex life.
Basically, I’d say in terms of the actual result, it doesn’t make a whit of difference what your body build is; sex can and in fact is very enjoyable no matter what your body build is. As long as you find the person attractive, and ultimately thats a matter of them as a person anyway, not anything shallow like looks.
