Being sore after that much sex is completely normal. How yellow is your discharge? If it's a very slight tinge of yellow it may be normal, but if its very yellow it is an indication of an infection. Is there any itching, or is the pain consistent/increasing? If so, you should go to your doctor. They can check you out to find out what kind of an infection it is (yeast infection, bacterial, etc) and how to treat it, or they'll reassure you that everything is okay. My gut feeling says you're just sore from so much sex, though, but you can never be too careful. Also, if it turns out that you do have an infection make sure to get your partner treated too. If you don't, he can just give it straight back to you over and over again.

Id say a slight creamy yellow although seems way more then he norm. There isn't really any itching or odor. It's not even that there was so muchhhhh sex but it did last a hour and then again about a hr later.. that of course was much shorter. It's been two months soooo I'd say there was a variety of positions.. so I'm sure that's where a little of the soreness came from. I'm also on the pill and my cycle will be next week so I may just wait...I did think about going to buy a over the counter cream. I've never had a std and maybe on yeast infection like my entire life.
