My sister and I have a very open, friendly, sister bond. We weren’t close when we were little girls, but now we are. As the oldest, she comes to me with advice, which sometimes is kind of awkward tbh. Anyways she told me, that every time she is really turn on and while having sex, her shoulder hurts a lot. All of the sudden. Has anybody here experienced anything similar and if so, what have you done to make it go away? I don’t know what to tell her, any help will be greatly appreciated!
