One of the lesbian women I spoke to, 24-year-old Amy*, told me she experienced verbal abuse from her own girlfriend, a bisexual woman who wanted them to have a threesome with a trans woman.
When Amy explained her reasons for not wanting to, her girlfriend became angry.
"The first thing she called me was transphobic," Amy said. "She immediately jumped to make me feel guilty about not wanting to sleep with someone."
She said the trans woman in question had not undergone genital surgery, so still had a penis.
"I know there is zero possibility for me to be attracted to this person," said Amy, who lives in the south west of England and works in a small print and design studio.
