Whenever my boyfriend and I get intimate, whether it be having sex or just a passionate makeout, I get hives on my butt, hands, and sometimes thighs and arms. They usually go away within the hour but they have lasted for several hours at times. People have said I'm probably allergic to some product he uses, but we can cuddle or sleep next to each other without problem. I just want an idea of what's causing it and if I should be concerned.
Don’t worry, what you have is called cholinergic urticaria. It’s a category of hives that results from high body temperature or sweating. You’re not alone; many women and men get this, sometimes after a hot shower, sometimes after exercise, sometimes after eating spicy foods
