Identity?

It’s not as dramatic as the title seems but I am wondering something. I’ve identified as bisexual for over 20 years and within the last like 5, I’ve noticed that I haven’t came across a man that I think is just extremely hot or if I ended up talking to one, it was because I was lonely and crazy at the time. I had gone through a major life change and got sober. Now, I have 100% continues sobriety from any mind altering substances for two and a half years. I’ve done a lot of work on myself and I’ve noticed that I just simply don’t want anything to do with a man. I’ve been talking to a couple of women here and there and I wonder if I’m just a straight up lesbian.

I know only I can say what’s me and labels aren’t everything but has anybody else ever been through this before? I was going to ask a lesbian group but they seemed kind of against bisexuals over there so I didn’t feel comfortable enough to lol
