Am I crazy?

A little background. I have only slept with two people. One being my ex, and the second being my current boyfriend. My ex was emotionally (and almost sexually abusive). It was a really horrible relationship, but it formed a lot of the ways that I now view and have relationships. 
I know there's the cliché that women are super attached and clingy after sex. I have never been that person. With my ex, I knew I was just being used for the sex and there was no emotion from him. I never felt needy or cuddly after. We would cuddle a bit, but it was never out of anything close to love. 
My current boyfriend and I haven't been together long, only a few weeks. We aren't in love or anything at all! But I know that I care for him very deeply. 
We have such amazing sex together. It's soft and caring. I can feel the emotion there. On Friday we had the best sex of my life. He was everywhere, holding me and looking at ME. Not through me like my ex always did. 
Afterward I felt so attached to him. I just wanted to touch him and cuddle him and never stop. I feel so much closer to him since! 
He's not very good at expressing his emotion and he's not huge on physical touch, but tries for me. He hasn't said anything about it, and I tried to give him space because I know that's what he prefers. 
Am I the only one who has experienced this? 
Am I crazy for feeling this way?
