Any way out? Love-making with my husband no longer turns me on

I’m married to my childhood sweetheart. We lived together for a few years then got married three years ago.

He’s a lovely and responsible man and I’m lucky to have him. We have a great relationship, apart from the physical side.

His love-making no longer turns me on as it used to.

I’ve never considered cheating on him though lately, I’ve told myself that if the chance arose, I might just go for it.

I love my husband very much and we have a cute one-year-old son.

He’s very extroverted and I’m sure he’ll be terribly hurt if this marriage breaks so would I.

Is there any way out of this.
