Fwb???

So, I kind of have a predicament. I've been hanging with this guy since like, Jan? And he's made it clear he just wants to be friends because he isnt looking for a relationship. So I'm like, ok, cool. Time went on & we've made out etc. etc. But I just don't feel like that's what friends do. But he's also said he didn't "want" to have feelings for me but he does. Anyways, the other day, he asked if I've ever been eaten out and if I liked it. So I was honest & said no, which is embarrassing (I'm almost 23 🙃) and he kinda said don't even worry about it, society thinks there's an ideal "age" to get stuff done lmao. So he asked that & then he said it was one of his favorite things to do (which is weird?? I thought most guys didn't like that??) I just don't know what to do. Like I don't want to be taken advantage of. And I don't want to have feelings. So do I just go in & chalk it up to an experience with no expectations? People keep telling me to be careful, I just think I'm too dumb enough not to see what's going on. He doesn't seem like the type of guy that would just use me?? Like he said from the beginning that he doesn't want to break my heart because he knows what it feels like. & TMI but sometimes when I even think about getting eaten out I get turned on (???) so I'm TERRIFIED what my reaction would be. This is so confusing I apologize 😂
