As the title says, the movie is about a gay guy and his best girlfriend, it’s not My Best Friend’s Wedding. The only part I really remember is the girl is changing clothes or something in front of him and they start playfully rough housing and it leads to them messing around a bit and then they realize that they both can’t because of their actual feelings. It’s an older movie maybe early 2000s late 90s perhaps, sorry I don’t remember much more than that.
The Object of My Affection (1998)?
I’d have to watch it again, but I’m about 90% sure that this is it, you can mark it as solved. Thanks so much!
Are you sure it’s not The Next Best Thing starring Madonna and Rupert Everett?
OK, marking “Solved.”
