K1 Visa - only been dating for 4 months, met twice.

My partner and I have only been dating since September and will have met for a total of 5 weeks in person, over the span of 2 trips when we apply for our K1 in December. Will this be an issue? I am from the UK and he is from the US. There are 9 years between us, he being the older. Replies are appreciated.
