I've just had sex with my boyfriend (not for the first time) and I have a swollen like part on my vagina. Its on the left and makes it uncomfortable when I cross my legs or walk. I really have no idea what it is and I'm worried. It looks really strange and like I said is uncomfortable.. can anyone help :s

Might want to go to the dr's just to play it safe and make sure its not an std or anything

Is it red... sensitive to touch... burns/itches/hurts?
