Seeking advice: mixed signals from younger guy

Hi.... to preface, I’m only into guys, but am attracted to bi guys, and a big supporter all around. Looking for advice on situation...

Me (32) currently back at university, through volunteering met a 22 yr old guy. At events we get along great and have in depth, meaningful conversation. He always seems very excited to see me and laughs at all my jokes.

We exchanged numbers and texted a bit, but didn’t see him for a few months. Last week, we volunteered at same event, ended up sitting and talking for 3 hours about sex, dating.... explicit details and deep emotion stuff. He showed me his tinder, only set to women and he was talking about his previous experience with women.

He was asking about my sexual interests, with my dating life, and I said I like fucking younger guys. And he was like “because of the prostate”. And I’m like... yeah there’s that. (Winky face horny devil emoji) It was all a fun, intimate conversation, and I felt really close.

But the few times i suggest we hang out outside school, he just completely changes convo or dodges question. It’s pretty clear he’s not interested hanging off campus, but only on.

What is happening here? Am I misreading, or is he absolutely interested in me but just conflicted? Why such an intimate conversation with no follow up of “hey let’s talk again!” Even for just friends.

TLDR: I openly fuck guys, I met younger guy,seems very interested in me, we had in depth conversations about dating and sex. He only mentions women but asked a lot about my sex life. Never wants to meet outside of school.
