does it count ?

My ex boyfriend who is a marine and I did it for the first time right before he left for the second half training , it was quick because we were worried about getting busted by my parents. Does it count as a first time? It was okay but idk if it could have been better or not ? He ended it a few weeks ago  due to him being in San Deigo and recently finding out he will be stationed there . It hit me hard. He has been there for me through a lot this past year with kidney issues and losing my little brother in January  people say move on but is it easy to move on from the first guy you fall in love with ?
