Is this normal?

Maggie
My boyfriend and I are in a long distance relationship we see each other like once every 2-3 months. So we obviously don't have sex often, is it normal that I feel pain at first? It feels like I'm having sex for the first time again kind of. The pain lasts for a minute then it's fine, but it sometimes stings to pee after, but when we consistently have sex I'm fine.. And it never bothers me to pee after. Could I be tightening up (as odd as that sounds) within a few months? My boyfriend says I feel tighter when it's been a few months, but any thoughts??
