Is it normal for a young couple to only have sex when they’re TTC?

Okay ladies, my fiancé and I only have sex when it’s time to try for a baby. Which is about 4-5 times a month. We are both young. I’m 20. He is 24.

Any other time of the month, we don’t have sex.

Is this normal or do we have an unhealthy relationship?

In my case, I don’t enjoy sex. Never have. With anyone.

We had sex SO MUCH when we first got together for about the first year. I mean every night. He only wants to have sex if I give him a blow job beforehand and put on porn.

I need opinions!!!
