A guy I want to hook up with always gets too shy and stopped us right before we are about to do it. I don’t know what to do.

So, there is this guy I’ve known for a while now and grew a close bond to (he’s mighty fine might I add). Anyways, a few nights ago we and a couple of friends had gone to a wild house party. There has always been sexual tension between us though neither of us had acted upon it. UNTIL we were at this party. it was so loud that in order to talk to each other, our mouths would have to be up in each other’s ears lol. Fast forward, after getting a little tipsy we started grinding and feeling on each other next thing you know we are having a full-blown make-out session in the middle of the dance floor. I grabbed his hand and took him somewhere a little bit more private. We started to make out again and I began to reach down and try to unbuckle his pants but for some reason, he stopped my hand and when I looked back at him his face was bright red. I was so confused because he was so confident beforehand. What changed? I don’t know. I thought it was kinda cute how shy he had gotten but I just couldn’t figure out why he was like that. He just left the room we were in and I didn’t see him for the rest of the party. I was kinda bummed out because I really wanted to do it. He also seemed like he was enjoying himself. I don’t know if it was the liquor maybe. I don’t think he even drank that much. He hasn’t spoken to me ever since and has been avoiding hanging out as a whole group. I’m just so lost lmao. Was I being too forward and scared him off?
