What happend during our makeout?

No offense, but I am thinking that you are just asking all of these questions just to brag about your recent experiences. Why would any ask all of these personal questions anyway ? To brag about it.

I doubt you even did any of these things.

It has happened to me when I was nervous and excited.

I'm going to side with dakadan on this one. Not sure about the kundalini energy thing but I would label it as major excitement rather than nerves. It's a great feeling but one that, I think, disappears with age and experience.

Kundalini energy is what I would say it is. It is an energy which can run up and down the body. I think it is in part an infusion of adrenaline due to his excitement of the situation with being with you. I know I have had a similar action in my body when I get very excited. Sometimes I can control it and have the energy directed, but when I'm most excited I just shake throughout my entire body.

I think he was just nervous. I have been like that before. It is no big deal.

It could be nerves and it may not be - not in the usual sense anyway. I had something similar happen once to me. I didn't even notice, but was told about it later. The moment was pretty vivid in my mind. We were dancing for the first time and we had an audience of nosy people from work. So I was trying to do two things. I was trying to hold her reasonably close given the situation and I was also trying to not quite press her against me. Apparently the result was that she could feel me shaking. I know this can happen when trying to remain very steady for a long time and the muscles aren't used to it. So while I wasn't feeling that kind of nervous, like stage jitters, she could feel it. I could picture that happening when making out the first time. A guy could try to be very careful and very deliberate so as not to appear to be rushing. If he seemed OK otherwise (like his voice wasn't shaky), then that's one possible explanation. I'd call it muscle fatigue. Either way, he has to be thinking this is a very important moment and not something to mess up.

most likely he is nervous but that can also happen when someone had too much caffeine lol so its probably nothing bad its just one of those things that happens to everyone

He's prob just nervous, or it be adrenaline mixed with nerves, eventually he won't shake, just give him some time.

defiantly its happened to me a lot I just meas he probably likes you he's probably nervous just don't worry about it don't ask him either it might bring him down

The one thing I think you can be sure of, is that whatever was making him shake like that, had nothing to do with you in a negative way. Almost certainly it was caused because he really liked you. Whether it was nerves, or excitement, or energy, or trying really hard, whatever, it had something to do with him liking you.

Yeah. He's just really scared because maybe he's been wishing for that moment ever since you got together with him. No biggie!
