DEAR DEIDRE: MY BOYFRIEND thought I acted out lesbian porn for him but now I can’t get the woman I did it with out of my head and I want a repeat.

I have been with my boyfriend for almost two years. I am 23 and he is 25.

We were out one night with my boyfriend’s friend and his girlfriend celebrating a promotion.

We got a taxi at the end of the night and headed back to our flat.

We had another few drinks and were dancing.

I was messing around dancing provocatively and the other guy’s girlfriend joined in.

Then my boyfriend and his mate suggested we do a striptease, then some other stuff together — they said it was things they had seen girls do in porn online.

We ended up acting out lesbian porn for them.

I am straight and have never even thought about sex with a woman, but it was so arousing and exciting.

My boyfriend is gorgeous and our sex life is adventurous.

I have no complaints there but he can sometimes be quite controlling.

We made out we were just doing it to please them but when I think back all I can think about is how good it felt.

I love my boyfriend but I can’t tell him that I can’t stop thinking about the other girl.

I really want to get together with her in private, but I haven’t spoken to her so I don’t know how she feels.

She sent me a DM on Instagram asking to “catch up” but so far I have ignored it.

The thoughts I am having about her are constant, yet I like them.

I see a gorgeous, fun, sexy woman who arouses me.

I don’t find other girls attractive and never have so I am very confused.

DEIDRE SAYS: It is easy to get carried away under the influence of alcohol but this sounds to have stirred up something deeper for you.

You now feel confused about your sexuality after this experience.

Please be reassured that our sexuality can be fluid so this shift may become more established, or may wane.

Take time to explore these feelings.

You were right not to respond to the other woman’s message.

You both have relationships to lose and would be far better off working out if you want to stay with your boyfriend first.
