Should I be very worried about my hubby's sexuality?

A few nights ago, my husband and I were out on a date night.

- DEAR COLEEN

My mum had the kids, so we had the whole evening to ourselves, enjoyed a couple of glasses of wine and some nice food, but then the evening took a bit of a turn.

We were having a laugh about things we'd both done in the past before we met each other and he admitted that he'd had a few sexual encounters with men. I think he expected me to laugh it off or just take it in my stride, but I was genuinely shocked and haven't been able to think about anything else since.
