Well...I've never had a dick in my mouth, so I'm not sure there is really a "taste" to it other than the taste of skin. (guys and gals feel free to correct me if I'm wrong) I don't mind a girl kissing me after she's been sucking my cock, I've never tasted anything different after she did. Also, it's pretty fucked up if I'd expect her to put my dick in her mouth, but then not kiss her for doing it. I do, however, find it very sexy kissing her after going down on her. There is an actual flavor there.
