Well, have you been?

yes.

Who with, and how do you go about it? What do you think your husband has noticed? Better change procedures or suspend activity for a while.

a co-worker. we mess around during the day and on Saturdays when we both work I leave my weight watchers meeting early and meet him before we start working. the hubby asked me last sat. afternoon (after hubby and I had messed around) if I'd had S-E-X with someone that mornign b/c I had weird discharge that looked like sperm (I know, TMI, sorry). I hadn't actually been with my lover that morning though. But the way he asked it made me suspect that maybe he's thinkin' something is up? and seriously, does he really think I'd have an affair and not use protection? anyways...yeah, maybe time to suspend the action. But my sex life with hubby hasn't changed at all. So, it's not like that would tip him off.

On a strategic note - I'm sure there's a simple gyn explanation for the discharge. You should be able to explain it to him and actually turn the situation to your advantage by making him feel guilty for asking such an indelicate question. He probably has had no other suspicions - if he had, his reaction would more likely have been something like, "Aha! I thought you might be cheating on me, and now here's the proof!" So he probably really has no idea.
