Risky Behaviors

4 modes of transmission for HIV

• Blood
• Semen
• vaginal fluids
• breast milk

Modes of transmission for HPV/HSV

• skin to skin contact (oral, anal, genital, manual, eyes)
• mucous membranes

Modes of transmission for Chlamydia/Gonorrhea

• fluid exchange (semen or vaginal fluids, oral sex)
• from hand to eye

The risk of all these behaviors is very conditional. Use of a barrier can reduce risk for many of these behaviors. It is difficult to put these in exact order of risk for this reason. Under specific conditions, without the use of a barrier, the risk continuum might go in this order for HIV transmission.

High Risk for HIV Transmission

• Anal intercourse (unprotected)
• Vaginal intercourse (unprotected)

Moderate Risk for HIV Transmission

• Sharing sex toys (without barrier or washing)

Low Risk for HIV Transmission

• Vaginal-vaginal intercourse
• Oral sex on a female
• Fellatio (oral to penile contact)

Almost No Risk for HIV Transmission

• Analingus (oral to anal contact)
• Manual stimulation
• Mutual masturbation
• Wet/deep kissing
• Dry kissing
• Solo masturbation
• Massage/hugging
• Fantasy
