Age gap relationship?

I (27f) met my coworker (49m) a few years ago we started casually dating about a year ago on and off. He has been hurt in the past and I haven't been in an actual serious relationship before. I have strong feelings for him and when I say he doesn't look his age, I mean it. Several friends have also stated that. I just feel like the age thing can be an issue down the line especially if I want kids down the line. He has had a vasectomy and has thought of reversing it but it may not be successful. Any advice?
