Will I kiss a man after he's just gone down on me? Hell, yeah. I find the taste of myself on a man's lips to be a tremendous turn-on.
Will I kiss a man after I've just swallowed his cum? Usually not, unless I've taken a drink of water first. Some men aren't very adventurous when it comes to their cum (that sounded kinda funny) and I would respect the man's preferences. If he doesn't mind it, then by all means, kiss me. If he'd rather I rinse my mouth, though, I wouldn't be the slightest bit offended.
Please though, guys, don't rinse your mouth after going down on me. Share the love. :wink:
Another issue that comes up (geez, just can't stop using that word in one form or another) is a man going down on a woman after he has come inside her. A man told me that to him, pussy tastes better than semen. I disagree (both are great to me), but if a guy felt this way, I'd much rather have him pull out and come on my back or stomach, so he isn't inhibited about going down on me after ejaculating.
