I woke up naked in bed with my fiance’s brother and don’t know if we had sex

DEAR DEIDRE: I AM petrified that I had sex with my fiance’s brother after I got totally legless and woke up naked in his bed.

My fiance and I are set to get married this summer but now I feel sick with worry.

His brother lives in Madrid and last month when I was due to visit for work he suggested I fly out a day early so he could show me around.

I’m 26 and my fiance is 28, His brother is 31.

Initially I felt a little awkward as I hardly know him, but my fiance encouraged me, saying it would be good for me to get to know the family better before our wedding.

So I agreed to visit early. His brother works as an English teacher in Spain and knew all the best spots.

We had a great day and met up with his friends in the evening.

I think I was too excited about being abroad and got pretty tipsy.

I do remember getting a little flirty. The drunker I got, the more confident I became.

His brother kept complimenting me and saying how I was “gorgeous and going to improve the family gene pool”.

By the time we ended up at a club everything was getting pretty blurry.

The last thing I can remember was getting into a cab with him.

Next I was coming around in his bed — naked. He was asleep on the couch in the living room.

When he woke up I demanded to know what had happened and he laughed at me saying, “Can’t you remember?! Let’s just say my brother is one lucky man”.

I keep getting flashbacks of me doing a striptease for him.

He insists he would never sleep with his brother’s future wife.

But the fact I don’t really know him and can hardly remember a thing is playing on my mind.

Should I tell my fiance?

DEIDRE SAYS: Getting so drunk you can’t remember a thing puts you, and in turn your relationship, in serious danger.

Please learn from this and the next time you feel you are drinking too much, stop so that you can make informed decisions.

Not being able to remember whole swathes of time means you wouldn’t know if you had sex or used protection.

This man says he wouldn’t have betrayed his brother, and you don’t have any evidence that you did sleep with him, but your guilty conscience is playing on your mind.

If you are still worrying, it would be good to visit your doctor and ask for a sexual health check as well as pregnancy test.

Still, telling your future husband would land him with a load of uncertainty but solve nothing.

Learn from this, stay sober, stay faithful and stay safe.
