What’s wrong with me?

So, I’ve been dating my boyfriend for 2 years now and we were always super into having sex, I’d always be the one who had the initiative to start the flirting, spinning things up, talking dirty, taking my clothes out of nowhere. But recently, I don’t like for him to even touch me 😔 I honestly don’t know what’s wrong because I love the man, he’s awesome to me and we’ve been best friends for the longest time.
