Yes, but you have to clarify on what you describe as an std and what exactly you are concerned about. You can catch "infections" without genital contact. I will say it loud and clear...You can catch an std and the transmission does not have to be from the genital area.
What is your age, sex, and sexual history? I need you to take it easy and understand that you are asking for a diagnosis. You do know that it is impossible to accurately perform that type of response. However, I can help you as long as you understand that stress can produce nearly any possible symptom.
Explain the area of concern, if you had them before, if they hurt, how wide are they. Give a little more information. You may feel free to talk in private.
Finally, please rest assured that whatever you are experiencing is somthing that can be treated, if necessary. You do not have anything fatal. It will snow in miami before you catch something fatal, if I could help it!
