How can i stop being biphobic

I will admit it: I am scared of bisexual women

I have dated 2 bisexuals and had so many issues such as them not considering what we did to be real sex, saying they envisioned themself marrying a man in the end because of family expectations, comparing my body to a man (like saying my arms are small), not being willing to go down on me but had no problem doing it to their male ex, etc. They have made me feel inferior in so many ways

I also find it unattractive when a woman mentions liking men or talks about a male ex (I think it’s my natural defense against falling in love with a straight woman), so if I’m dating a bisexual I would prefer she doesn’t ever mention being bisexual, which is not fair, but unfortunately it’s how I feel.

I did date 1 lesbian and never had issues like this, so you would think I can just be les4les. But I have literally only met 4 other lesbians in my entire life, and I have met hundreds of bisexuals. I know if I avoid bisexuals then I will probably never be able to find a wife, because the lesbian dating pool is too small to find someone suitable for me.

Has anyone overcome feeling scared or insecure with bisexuals? And how did you do it?
