Sex has been hurting... like a lot, it used to be only when I did it everyday and so I got sore but now every time we have sex we have to start super slow until the pain goes away... we use spit as lube and I can tell when lubrication is a problem and it's not. I'm 17 and have had a pretty good amount of sex so I have no idea why suddenly it hurts this much... (we always use condoms and recently I got the depo shot but the pain was occurring before the shot as well)
