Does anyone else feel so much better after sex?

Not like immediately after that's obvious. But like I'll be having a bad week, I'll get some and wake up the next morning in a better mood than I've woken up all week. Don't let him have slept over either, my insomnia only woke me up once last night and I woke up refreshed.

I feel like the dick can't be that serious. He did try something new last night... It's literally just sex. I don't think it should be giving me a pep in my step like this...
