So, my boyfriend and i tried to have anal sex a while a go.. Like a week, and it didnt work out because i am still too tight. So, he washed up completely and we finished vaginaly. Within the next week to now, my right labia mojar near my anus has been swollen and tender. But the color is the same, no odor and no itching. It feels like a knot. What could this be? We tried having sex last night and it hurt real bad when he first went in but after he was in, it didnt hurt.
