Sexual performance related anxiety in homosexual relationships

I am a white heterosexual cisman and I am constantly haunted by intrusive thoughts related to how I will perform or be perceived in bed.

Whenever I see depictions of gay - especially lesbian - relationships, I imagine the relationship being a lot less toxic, less detrimental to each other's mental health and - most of all - less prone to performance related anxiety.^[I am fully aware of the hardships that homosexual people have to endure throughout their lives. This is an unrelated matter.]

Is this just prejudice^[We all know how media and pornography paint a certain picture of homosexual relationships to serve heterosexual people.] or is there some truth to it?
