I haven't masturbated in 11 days. I'm a guy.?

As my question states, I haven't jacked off in 11 days. I usually would masturbate everyday, every other day, or 2-3 days later.

Why did I stop?

I did some research that masturbating releases dopamine and excess masturbation will override the brain system and continues to keep our body in 'fight or flight' situation. I personally don't really know what that situation feels like, though I may have experienced it. But I'll say that I never felt nervous, angry, or scared when I masturbated everyday... and being constantly in that situation didn't sound too good to me. So if someone can clarify what that means I would appreciate it.

And someone told me that excessive dopamine in the system will hinder memory temporarily. After the levels are down, it'll be fine. But during that 'high' period, I heard it really hurts the memory. And I'm guessing over time, it'll have some consequences. Again, if someone can clarify this, that would be great.

I know that anything excessive isn't good and I felt like I wasn't doing my body any good by masturbating everyday. So I decided to give maybe about a week break. But as week passed, I noticed some changes.

I think I became a bit more cranky and angry (I'm guessing it's the increase in testosterone) but other than that, I feel much better; even with less hours of sleep, I feel strong and energetic. I'm less tired during the day. I also feel more confident around girls and even feel like I'm getting more attention.

I haven't had any wet dreams lately, and to avoid it, I've been sleeping on my back (so my penis doesn't get stimulated by the bed).

I don't know if this is just all in my head. If anyone abstained from masturbation for awhile and experienced some changes, I would greatly appreciate it if you shared them with me. Or if anyone has some questions I'd be willing to answer.
