Can you be gay/bisexual/lesbian and a Christian?

I don't mean to start up anything... But I've been saved for a year now and I haven't been with anyone. I used to be bisexual and get with girls and guys but now that I'm saved I'm not sure if it's right or not? I know in the Old Testament of the bible it talks about it not being okay to be with the opposite gender but I don't recall it saying anything like that in the New Testament? (Which were supposed to live by now in days) I find guys SO attractive but I also find myself having girl crushes...
