I got really aroused/turned on by kissing and some touching (clothed) with my boyfriend. How bad is this? I’ve been crying about it and feel sick. I feel really bad about it

I’m 18F and my boyfriend is 28M. He’s my first boyfriend and I’m a virgin (like I’ve never even done anything sexual before at all). I’ve only masturbated by myself before and that’s it. This what we were doing: I was sitting on his lap and he was kissing my neck and rubbing his hand on me (not exactly on me down there but around that area). Both of us had clothes on and everything. It’s not like we were really doing anything super sexual, he was just kissing me and rubbing his hand on my body. We didn’t have sex or anything so this is all that happened, but I’m feeling really upset about this to the point where it’s making me feel sick. I try not to think about it but I start crying again.
