Confusion after having straight sex? Has anyone else experienced this?

I identify as female and I've been mildly attracted to men my whole life. I've always wanted men to like me and I waited until I found someone really special until I lost my virginity (which was about a year ago), I thought straight sex would be great and I fantasised about it a lot beforehand. I've been incredibly confused since having sex. I had a very strong connection with the guy I had sex with and I felt comfortable with him, I also wouldn't describe the sensation as a feeling of guilt, but it just felt so wrong. I was anticipating having sex with him but when it actually happened I wanted it to end, it didn't feel physically uncomfortable but emotionally unnatural. I didn't want to have sex with him afterwards and, to his dismay, I ended our relationship abruptly. In the year that has elapsed I've constantly been pondering relationships and attraction. I don't look at men the same way anymore and I have a desperate desire to make out with someone of the same sex. Looking back at my younger years I would never have considered my self to have had a crush on another girl but if I really think about it my girl envy might have actually been revealing something more significant. The female friendships I have had are often very immersive and sometimes relationship-like. I daydream about women and no longer experience any sexual arousal at the thought of men. I'm just overwhelmed at how much my entire perspective on relationships has swayed since I lost my virginity. Is this abnormal? Should I try having sex with another male? How could losing my virginity have created all of this confusion?
