I (F26) don't know if it extends to a fetish, but my boyfriend's (M26) biggest turn-on is when I wear a thong. He gets very excited when I wear them, says how good I look, cups my butt when we lie next to each other, while playing with the material. I generally don't have a problem with it, and I like the compliments he dishes out.

However, I admittedly do find thongs uncomfortable and would prefer to wear full cut briefs. When we had sex the other day, he seemed disappointed that I wasn't wearing a thong, and I said I wouldn't wear one every time. He seemed to accept this but when we were lying next to each other that night, he said how good I looked in one (again).

I went online and decided to buy a male thong for him, so he could experience wearing one and feel the discomfort levels. When he came home from work, I texted that I had a surprise for him. He was obviously excited, and when he got home, I gave him the thong, which I'd wrapped up in gift paper. When he opened it, his face dropped. He asked why I'd bought him this, and I just explained that maybe he should experience wearing a thong everyday so he knows what it's like. He immediately got cold and said he hadn't pushed me to wear one, just expressed a preference, and I was trying to make him feel humiliated about the turn ons he has.

I tried to talk to him, but he's clearly still annoyed. I spoke to two friends; one found it hilarious, while the other thought it was unnecessary, especially because it's not exactly a "weird fetish".

AITA?
