Love my husband but can't stop fantasizing about taking my friend's v-card

I [24F] recently posted about dealing with a fantasy involving my friend [21M] who's been actively simping over me for the past year, but since I got a ton of hate on that sub I'm gonna try my luck here.

Quick disclaimer: I am NOT planning to cheat on my husband. We've been happily married for 5 years so I respect him enough not to turn him into a cuck over some fucked up fantasy. I just don't know what to do with these thoughts even though I know it's already emotional cheating.

I don't have any romantic feelings for this friend, but I have a pretty strong fantasy about taking his virginity. He's a short nerdy guy a couple years younger than me, and on top of that has zero experience with women which basically makes him my type.

I don't know what to do because for the first time it's not some random fictional character I'm fantasizing about but a close FRIEND I've known for a long time. I never thought about him that way until recently when he told me he's never gone beyond kissing anyone. Some of our friends literally assumed he was gay/asexual bc he's never had a gf or at least tried to get one. So with how actively he shows interest in me it genuinely feels like I'm the first woman he's ever been attracted to.

Hopefully I don't get called a slut or a cheater right away and instead get some actual advice from someone who's been in a similar situation.
