I'm 17, I've been masturbating since I was like 13, and sexually active since I was 16. Sometimes when I'm masturbating I'll just feel kinda gross and then after I finish I'll just be kind of sad. Same with sex, except it's a bit worse because I'm actually invonved with another person. I really have no idea why! I've only ever had sex with one person and I love him, there's no reason for me to feel like that. And then like 10 minutes later I'll feel better and I'll want to cuddle. This also doesn't happen every time, it's only sometimes, but it's almost like a feeling of regret even though I know that I don't regret it. Not sure why. Answers please. Thanks.
