Depends on if both sisters used to both be gay brothers or if they were straight until their transition.

If they have both been gay since a young age, which is genetic in a way that still hasn’t been made completely clear but is definitely genetic, their transition makes sense since it’s now socially acceptable in Hollywood to be trans and could be a way for them to sleep with the straight men they have always naturally loved.

Now, if they were both straight guys who opportunistically transitioned when it became profitable and socially acceptable, it’s because some time during their sexual development and ego development, they developed a fetish for cross dressing erotically or trans porn. The issue is that this type of sexuality is taboo socially because it’s a type of sexual narcissism, however Dr. Anne Lawrence suggests we should phrase it that these trans women are ‘becoming who they love.’

Why is it important to know? The latter category have narcissistic personality traits and bourgeoise/PMC/wealthy narcissists have separate class interests from the working class, who don’t want an increase in legal bureaucracy and the destruction of gender roles and the family form, which are all the goals of neoliberal capitalism and exemplified in propaganda via the sudden emergence of weird, screechy rich trans celebs in tabloids while their twitter-obsessed teen daughters start using ‘they’ pronouns and take hormones that will destroy their fertility.
