Pregnancy

I lost my virginity when I was 20 years old I’m now 21 and every since I’ve been having unprotected intercourse it only has been with one person since the day I lost it, I feel as long as I’ve been having unprotected sex which has been for about 2 years to be exact that I’m not able to have kids, which is weird for me I think my partner is a bit too old to make babies not saying I’m ready for one, but I want one in the near future. Is it me or is it him being much older than me?
