Well, I'd say it's time to talk about some things. Either your husband is gay and hasn't accepted it or has been forced to hide it, or he's bisexual. Either way, he cheated on you. Whether you work it out or not, I hope you can get some answers. FYL.

I'm assuming he thought that was the correct hole.

Well that's a shitty situation. Sorry he was such an ass. Ok no more puns. Cheating is cheating OP, hope everything works out for the best. Sorry!

Well, at least he wasn't lying when he said you're the only woman in his life...

I’m pretty sure there is a perfectly reasonable explanation. I’m sure all that happened is they both happen to be naked together for no discernible reason, when the other slipped, fell and landed on your husband’s dick. It could happen...

Ah well, it happens to the best of us.

See what happens if you don't do anal with him?

Bummer.

thats a sign you should talk more
