I have mixed feelings about sex?

Today I started to feel bad about not being a virgin. Protected seems a manipulated act: it manipulates the result of having sex which is having children. I feel uncomfortable thinking about it. It seems like it is a huge deal, and I can’t just think of it as a ‘fun act’ without thinking how ‘wrong’ it is to use it as a fun act. I am pretty sexual and I have urges, yet I can’t stop thinking I’m being reasonable in my way of criticizing sex. Sex without the purpose of having kids seem very altered. I won’t stop having sex, but It’d be great to have some opinions on the subject from Flutherland so I can be enlightened!

Thank you
