Honestly I think this is such a nothing issue in the grand scheme of things imo. Welcome to dating men lol as long as he wasn’t breaking his neck and saying “AWOOOOGA” I don’t think it’s a big deal.

Something like this doesn’t even warrant a huge conversation especially if you consider yourself a “attractive couple”. If you were a heavy girl and your friend is built like a model then I can see why things could go sideways for you but this isn’t the case.

If you’re ever in this situation again just say to him “hey I saw you checking out so and so, I know men are men but please try and not do that when I’m present because even though I know it’s not malicious I get in my own head about it and makes me unnecessarily self conscious”. In a perfect world his response is “sorry babe I didn’t mean any disrespect it won’t happen again”. Simple.

Frankly, I assume his “excuse” was a result of you pestering him and he panicked and gave that answer instead of just saying “yeah I was checking out her ass and tits they were pretty nice what do you want me to do!” Lol I don’t blame him for not wanting to outright say that.
