wierd bruises

My girlfriend has a few bruises on her leg that appeared recently.  Her ex had gonnorhea (Gonorrhea), nad maybe something else Im not sure.  I am afraid she may have gotten something from him and not told me.  If there is anything that may causes bruising please let me know.  Also the bruises cause her no pain, and they fade in and out from really dark and purple to barely brown.  Thank you.

No STD causes bruises. If you are concerned that she got something from her ex then she needs to test. But what is going on now has nothing to do with a STD.

It's probably from holding onto her legs during intercourse it's a normal thing don't worry but still i would get yourself checked just incase she did give u something.
