When you hold celebrity interviews in a little jacuzzi, things are bound to get dirty eventually.

Such was the case when Olly Alexander was a guest on the BBC's The Paris Lees Sex Show, a program dedicated to taking a closer look at the many different aspects of getting it on.

Paris invited the openly gay Years & Years frontman into a giant bubble bath to find out what he finds sexy.

"I think if you've got confidence and self respect, if you have those two things, I'll probably be up for having sex with you," Alexander said.

They also discuss the importance of teaching gay sex education in schools, as Olly explains he used to draw diagrams of two men having sex in high school because he and his friends couldn't figure out where all the dicks go.

"What happens with that dick?" he remembers asking. "Where does it all go?"

"It's just too many dicks!" answers Paris, before offering the singer a pickle to chomp down on.
