Hi Doctor,

I went to several sex workers during the past two months and I just touch them, kissed them on the mouth and head area and neck, and just suck their breasts.( but do not notice any blood or sores)

My quetion is, may I contact STD?

My testicles are a bit itchy nowadays, no sores however a little red due to scracthing maybe? ( Is it because I do not wash them properly-- may be it is because of the body soap that is still unwashed that makes it itchy? Howevere I washed my testicles throughly lately, but still itch now.?

Thanks Doctor for your time and answer.

It is possible, but unlikely. The most likely way to transmit a sexually transmitted infection is through genital contact. Unless your genitals came into direct contact with your partner's genital area or mouth, you should not be worrying about STIs.

A basic model for STI transmission describes transmission in two different ways: either through contact with FLUID (like semen or vaginal secretions) or direct skin-to-skin CONTACT. Here's the breakdown:

STIs spread by FLUIDS:

Gonorrhea, Chlamydia, HIV, Urinary Tract Infections/ Nongonnococcal Urethritis, Hepatitis B (HBV), (Hepatitis is also found in saliva, so kissing is a risk), Syphilis Cytomegalovirus (CMV), Trichomoniasis (Trich)

STIs spread by CONTACT (skin-to-skin):

HPV/Genital Warts, Herpes Simplex Virus (HSV), Molluscum Contagiosum, Chancroid, Syphilis, Crabs/Pubic Lice, Scabies

If you have questions about symptoms you are experiencing, see a doctor. You could have something as simple as jock itch, which can be resolved with appropriate treatment, so see a doctor and stop scratching.
