strap on

So last night I let my gf strap me for the first time. It was an amazing experience. My issue is, I've never considered myself gay until last night. bisexual, yes! gay, no! But I'm in love with her. the way she smells,her smile,the tone of her voice everything. so my question is does that make me gay? I literally have no desire to be with a man anymore. anyone have a similar situation?
