I’m 19 and have been questioning my sexuality since early last year. When I was younger I had sexual activities with girls and I actually liked it, but I was driven and scared away from it by Christianity. It was hard for me let go of the urges and I was ashamed, but over time it became easier. I left it in the past and have only had feelings and been relationships with boys (in my second one now), but I still get a “switch flipped” with female to female intimacy and still find girls hot on the “sexual” spectrum. I can’t say for sure on the “romantic” spectrum. I’m I actually bi? And if so...I’m afraid to accept it because of my religion.
Bi with a slight lesbian bias I suspect. Don't worry about it, question the truth of religion not your sexuality. Who you are is real, religion is just a construct We can't choose who we fall in love with or who we are attracted to. Regardless of gender just make sure you are with someone who makes you happy.
There's no need to label yourself. You are with a man at the moment but a woman might sweep you off your feet next. Or another man. Or the mam you are with now. Who knows (and really who cares as long as that person makes you happy)
If something conflicts with your experience then the chances are it has been disproved. In which case ditch your present version of your religion as being in error.
As for your sexuality, does it really matter ? Whatever label you give yourself you are still who you are.
