I have a question regarding STDs. My current BF said he thinks he may have gotten something from me, but we both have been checked last summer and never have had any former STDs. He said it looked like a pimple, but was still concerned it may be something more. We first slept together on Jan. 14th and he noticed this on Jan. 22nd. I have not had any symptoms of anything. I do have an appointment to be checked, but is this something we should be really concerned about? Or could it be just that- a pimple?
