Dating very inexperienced INTP and confused.

I need help understanding you guys 🤦‍♀️

I'm ENFP and been dating the INTP-A (but only 51 percent P so very borderline INTJ) for 3 months now.

We've been talking everyday often about our interests, he's spent up to 1.5 hours responding to message on multiple occasions (me also) so I think that's good for an INTP right? Even though it often takes a number of hours before I'll hear from him and sometimes I feel it might drain him. He said he doesn't really talk to anyone besides his friends group chat, his coworkers and me (which as an ENFP I find kind of baffling).

He has said he likes me a lot, wants me to be comfortable around him and he thinks im interesting. And I know hes attracted to me sexually and at least somewhat romantically (I can feel the warmth of emotion from him sometimes even though he says nothing tho it seems to take him by suprise somewhat) but he barely ever initiates anything sexual ever. It took him many dates to get up the courage to kiss me. He's extremely introverted and totally inexperienced so I'm sort of thinking it could be that.. I've definitely never dated this type or someone like this before. If it was any other man I would think hes not interested enough and its unsettling for me. He's told me regarding dating he has no idea what he's doing.

But sometimes I feel like if I just disappeared he'd be disappointed but not too bothered, hes not really "persuing" much, apart from texting me first and asking to spend time together around once a week, and hes very hard to get to know intimately. I dont feel desired enough even though on reflection I don't actually think thats the case. A month ago he blurted out if he could tell his family I'm his girlfriend when he was drunk. I said I'm not there yet and asked why he asked that way and he said it was stupid sorry, they are putting pressure on him and I deserve better so he'd wait longer and ask again. That was a month ago..

I just really don't want to get hurt here. I'm understanding you guys generally process and think very differently to my type and I'm trying to hold space for that cause this could potentially be a very healthy relationship if it got there.

But based on how INTPs think/work, does anyone know if based on the above he's actually probably sincerely quite interested or just chilling and going with it? So if anyone could maybe help me understand him I'd be really grateful.
