Is this common

So i never used to watch porn but once I got pregnant and at around 20 weeks I would always randomly get horny and my husband is at work so I started looking through porn but I always seemed to end up watching lesbian porn and master bating I’m not a lesbian and I never really find myself attracted over girls in a sexual way but I always end up on lesbian porn I personally find girl and boy porn awkward but when it’s two girls and a guy I find it more entertaining does anyways else come to this when watching porn?
