I've been starting to explore my bisexuality outside of Reddit for a few weeks now. I joined one of the gay hookup sites where location services are a big part of finding hookups. I haven't gotten the nerve up to actually meet up yet, but I'm close.

I live close by to a couple of my best friends, who happen to be married to each other for close to 10 years with 3 young kids (oldest is Jr. high). As I'm scanning the map, there's an icon right on top of my friends' house and there's the husband's penis front and center letting me know he's looking to receive a BJ. I know it's him because in addition to the location, his age matches up, he has a distinctive tattoo that's fully visible in the picture, and I recognize the background as being taken inside their house.

I definitely didn't expect to find him there and I don't think I'll be able to look at him the same way when I do see them again. Do I say anything to my other friend, his wife? He's not out and neither am I (I don't want this to out me as bi either). She caught him cheating years ago with another woman and they were able to work thru it - this was before I knew them. I'm confident in my poker face being able to hide what I know. I also don't want her to catch anything from him when (I assume) she thinks he's being monogamous. Just to make it clear, I'm not attracted to him so don't suggest that either.

Do I say anything to her about this? I have her email I could create an anonymous one to send from if needed... I am -heavily- leaning towards not saying anything though due to the kids, and my being very non-confrontational. I'm frankly at a loss here, never been in a situation remotely similar and wish I hadn't seen this! What would you do?
