I think that he feels constrained by having one lover, in that he's supposed to be there for her, but he knows that she's cheating on him (you were hanging with a crowd...) and shows her that he doesn't need her.
"just lay back and think of England" was said to victorian women as they were not supposed to enjoy sex, it was for the man's enjoyment only, the woman's job was to bare the child. Of course that's absolute bollocks today, but it could mean that he doesn't enjoy sex with her, but it's his duty to her, perhaps he feels guilty about cheating on her.
But then he lets it out "I was born to be a dancer" it's like he was born to be free, what he wanted to be, and there is a paralel with sexual desire there as well. A "dancer" might be someone who has a lot of sexual partners, but he justifies it as he was born like that.

That is my interpretation anyway
