Yes, You've been "awakened";
to answer Your question: it's quite 'normal'......and if it didn't 'feel good' we wouldn't want to do it......and the human race would die out.
(but save those feelings for Your committed relationship - keep it 'special' and an expression of love)
How old are you if you don't mind me asking? Anything that we do and we like it and it feels good is going to awaken that desire to keep doing it, right?
