Accidentally gave my girlfriend a hairy butthole, not sure how to fix it.

Hey guys, I need some help.

I’ve been using topical minoxidil to grow a beard because people keep saying I look like that kid from The Suite Life of Zack & Cody even though I am on 200mg of TRT. I apply it after showering at night, but my girlfriend and I usually have sex before bed, and I’m into eating ass (don't judge).

Here’s the issue: despite barely seeing any progress on my beard, I’ve noticed a lot of hair growing around my girlfriend’s butthole. She has no idea what’s going on and is freaking out, and honestly, I’m not too happy about it either. I was all for eating ass, but now there’s too much hair, and at this point it’s a huge turnoff because it reminds me of eating a man’s ass.

If I stop using the minox, will her butt hair go away, or am I stuck with this? Not sure if I should tell her the truth? I don't want to admit it’s my fault. I'm honestly thinking about just breaking up with her. It sucks because she has one of the best buttholes I have ever seen on a woman.

Looking for advice.
