He could be infertile?

My boyfriend is 29

Been married and divorced.

He tried having a child with his ex wife with no success.

She cheated on him while married and got pregnant by someone else.

I'm 19.

I want children eventually and I'm worried that we may not be able to conceive.

I get that, there's adoption and I'd be open to it but, I would want my own child too... just to experience pregnancy and things.

I'm so torn thinking about it and we aren't even TTC.
