Hi,

This might be a coincidence, but I've noticed that 2-3 days after I have seen my boyfriend, who lives far away and I only see once every 2 weeks, my breasts are sore for a day. I'm on the pill, 3rd week, but it actually happens almost every single time I see him. So I linked the two, and say that it's all the hormones going around from the sex.
I do have an appointment with my GP next week and will mention it, but has anyone else experienced this?

I haven't experienced it myself. But that seems like a reasonable explanation. Still a good idea to mention it to your dr, just in case it's something more.

I wonder could it have anything to do with the actual sex?

I don't think so, because he doesn't squeeze my breasts or anything(sorry for the details). The only thing he does is lick and lightly bite my nipples. Which I love!!
