I'm christian too (sort of) I have sex when I want to and I don't usually care.
I think I sometimes feel guilt for it because of how i was raised christian but I think its natural. Some christian churches are against anything sexual until your married. They even against masturbation or porn, which isnt sexual intercourse. I don't get why.

I think you should do what you want but it might be harder to be sexual if your going through a lot of stuff.
