Feelings???

So I've been talking to this guy I met on tinder for about 3 or 4 weeks. We met up twice and the second time we hooked up (that was my first time having sex).

Don't worry I'm not dickmatized or anything but it's just something I've noticed from my time with him, even when we aren't speaking and we're just quietly on a drive I always feel comfortable around him and I get an electric spark feeling whenever he touches me ( hand, kiss, whatever). I noticed it the first time we met but I just figured it was bc he touched my hand out of nowhere.

I know I'm not falling deeply in love with him or anything bc normally it takes me a while to really start liking someone, but this is the first time I've ever felt like this about a guy?

Like I'm not stressed over this, I'm just curious if anyone has felt something similar or have an idea of what it could be lol.

Also I've gone on other dates with other guys and non so far give me the same feeling.
