Felt horny after a decade!

It had been a long time since I hadn't experienced this feeling, almost forgot how being horny feels.
In adulthood my pmo consumption were due to anxiety, boredom, not having other options, etc but not because I felt horny!

I exercised today and after that this feeling arose. Although I know its natural and I'm happy about it, but it made me search for some vanilla pics which made me nervous about future possible relapses.(suggestions to avoid?)

The energy was high for the rest of the morning. Then I took a nap because I was exhausted and I had a wet dream. My horny ness vanished after that and I felt a little heavy in head.(normal?)

One question. Do you ejaculate in your wet dreams? I mean I experience ejaculation but no semen comes out.
