I find it hot, its a sure fire sign of being excited (or having an std lol).
I have had people tell me no blowjobs since I'm leaky. Took offense to it, but got past it, blowjobs are just foreplay anyways.
If you got me going, I can lube anyone up and have penetrative sex with them for 20 minutes before drying up. It will never happen unless I'm in a commited relationship of course.
I find a bottom that precums really hot as there is nothing like seeing a person react physically to you taking the plunge in their ass. You can fake groan all you want, but that leaky slick clear stream means that they are feeling you. Like wise most bottoms can use that to their advantage to speed up the tops enjoyment. I personally don't like being dug out for too long, and that will get most tops going ... going ... gone.
