BF & I got drunk and things turned sour

I’ve read other posts asking for advice and, well, I need some now...

This is the first time I’ve ever gotten drunk with my boyfriend of 4 years. I’ve had sips with my friends but I always keep my wits about me.

Story goes:

I got drunk and my boyfriend was only tipsy so I started to talk and be sassy (I apparently like to race now) and he asked me “Are you feeling horny?” Because apparently wine makes you horny and I am in touch with my sexuality. I replied “No” and kept on being silly.

So, after a few hours I’m sitting and talking to him with my legs crossed. My boyfriend decided that it would be a good idea to poke my vagina and I told him that I wasn’t turned on. He didn’t stop. So I got serious and I moved his hand away and told him I didn’t want to do anything because I wasn’t in my right mind.

He stopped but not before telling me that he “knew” I was horny and was only trying to prove that to me... but I was never horny.

This hits me hard because I’ve been in situations where I’ve done things that I didn’t want to do by a guy I had dated before. My bf knows about it too.

I know we both weren’t in a sober state but this still bothers me so much. Don’t get me wrong, he’s an AMAZING guy. Guys like him are very rare but this is something new, something that doesn’t seem like him.

I’m just afraid that maybe this is who he is deep on the inside and his kindness and love for me is a facade.

Any advice?
