Is my boyfriend gay or shy?

I'll just describe him and his actions and any Insight would be super helpful! he's shy but we've been going out for a little over a two months, almost three maybe. We started making out a couple weeks ago and i grind and hump on him and he'll sometime jump back. I give him hickies. He says it feels good and I don't make him uncomfortable but he never touches my butt or holds me tightly while I'm grabbing and pushing him closer to me. I sometimes guide him hands to my body but it always just ends up my his side or on my arm. I just don't understand why he wouldn't be grabbing me too and humping back. Could he be gay? He tells me he loves me but I'm confused. This is my first serious boyfriend by the way so please help
