Hi,
My girlfriend gave me oralsex (blowjob) before 3 weeks with the condom completely covered. I suddenly noticed and I find that my right testicle is little larger than the left testicle. Often the right testicle keeps moving down a bit . Sometimes it is little painful. I have a fear that I might have got some STDs. I am unable to concentrate on my work and I am really disturbed. I have a doctors appointment tomorrow, however would like to know if this looks a very troublesome situation. Have I got contacted with any STDs? Please advice. Is there a chance that you might get affected with STDs even with the protection measures you take.
