Libia majora lip swollen

So my boyfriend and I are somewhat long distance and don’t see each other as often as we’d like to. Well he’s staying the weekend over so naturally we start to get hanky panky and the first time was amazing. The next morning I’m showering and notice that my right labia majora is swollen, like pretty swollen. It has like one section on it that’s like puffy. I don’t know how else to describe it. I’m thinking it’s from one position we do where I’m on top straddling him and grinding back and forth pretty hard because we both cum easily from that. Well we did it again that day and using some lube but we did like seated backwards cowgirl. I’m keeping an eye on it and it still seems to be swollen but just on the right lip.

I just wanna make sure because I never have issues down there like this. Would the swollen-ness most likely be caused just from the rougher sex we have? It’s a little sore but isn’t ridiculously painful, just a little uncomfortable to wipe or touch. Will it go away on its own?
