Then I blurted out that I had little chance of fathering children. At 21, I knew she was too young to really understand.

Still with my ego dented, I spotted her again in the same pub six months later.

Once, I pulled off our double-glazed front door from its hinges after a minor row with Maria had escalated.

I tried testosterone patches but my skin reacted badly.

When I was first diagnosed at 25, I had never heard or read anything about testicular cancer.

But while on holiday in Corfu, my right testicle suddenly swelled up to three times the size of my left one.

When Maria fell pregnant again, in 1999, we were overjoyed. I was still having regular scans and in mid-August doctors saw something unusual on one of them. Everyone in my family cried and I was convinced I was staring death in the face.

They diagnosed testicular cancer in my left testicle. The odds of suffering the disease twice were very low, about one per cent. But doctors said there was a future and I had my sperm frozen so that Maria and I could have more children if we wanted.For months beforehand, I had suspected something wasn't right because I had felt a dull ache, but there was never any serious pain.So I dismissed my fears, convinced it was a sporting injury.But I refused to give in and today I have never felt so full of energy.I've always been fit and active, playing rugby and squash, or going to karate classes.Desperate to raise awareness of testicular cancer, I started my own campaign - Check Your Tackle - by power-walking in minimarathons around South Wales.
