Ichy Anus.. STD? Help.

I had protected sex last night, and today I found I have an ichy anus.
Could think be linked? Maybe I have an STD?

STDs are nothing to take lightly, if you're concerned see your doctor immediately.

If that were true, I'd still be here.

I dont think I need to stress the importance of this. GO GET CHECKED!!! Better safe than sorry, for it may only be something as simple a rash that would require baby powder to dry out.

My guess it is itchy probably due to irritation from being stretched and not using enough lubrication. However, if you are concerned that you have a STD then it is best to get it checked.
