Age gap...

Anonymous • 24, married, TTC for almost 3 years. Love the app, community, and support from y`all lovely ladies.
I'm married to a man who is 10 years older than me, and a few friends of mine said that it was too big of an age gap. I don't think it is. I've seen many ladies on here with age gaps too. So I'm interested, what do you think is too big of an age gap? 10 years? 20? 30? 
Please don't judge people on what they think is ok. That's not what I'm posting this for. I just want to see what other people think. :)
