Do you know what?
I don't really overthink the risks of sex work. There are risks everywhere. I'm more likely to be totalled in an RTA than I am to catch an STD (especially as I drive all over the UK). I get checked at the GUM. I do OWO. I do rimming. I CIM/SWALLOW.
If people are so concerned with the risk factor I think their services should reflect that or they should be in a different profession.
I have entertained bi sexual men, women, people who go to GBs and homosexual men who wanted to 'try heterosexual sex.
I've never had a booking with a transgender woman but I would accept one without hesitation.
I can't see why anyone would be discriminated against based on their sexuality or what body parts they have or haven't got. As I said previously, we have a right to refuse bookings for any reason but assuming transgender ladies are more likely to be high risk is ludicrous.
