Pregnancy Risk Assessment: Dry Sex

"Dry" sex -- often called frottage, grinding or dry humping -- usually will NOT pose any risk of pregnancy, nor risks of sexually transmitted infections.

There are some scenarios in which it may pose risks, primarily if one or both partners were not clothed. If you're worried if dry sex may have posed a risk for you, follow through the questions and answers below.

Have you engaged in dry sex / dry humping while both fully clothed, without any bodily fluids - pre-ejaculatory fluid (pre-cum), semen, or vaginal secretions - soaking through either partner's clothes?

If NO bodily fluid soaked ALL THE WAY through the clothes, then you have NO risk of pregnancy.

  • If bodily fluids DID soak through, keep reading.

Have you engaged in dry sex / dry humping while fully clothed, where some bodily fluids - pre-ejaculatory fluid (pre-cum), semen, or vaginal secretions did soak all the way through either partner's clothes?

If bodily fluids soaked through only ONE person's clothes, then you have NO risk of pregnancy.

  • If bodily fluids soaked through more than one person's clothes, keep reading.

Have you engaged in dry sex / dry humping while fully clothed where bodily secretions of any kind soaked ALL THE WAY through both partners' clothes, or when clothing was not worn at all?

If NOT, then you have NO risk of pregnancy.

  • If bodily fluids DID soak all the way through both partners' clothes, or clothing was NOT worn, keep reading.

Were the bodily fluids that soaked all the way through both partners' clothes ONLY vaginal secretions or menstrual blood?

If YES, then you have NO risk of pregnancy.

  • If NO, keep reading.

Were the bodily fluids that soaked all the way through both partners' clothes semen ("cum" or ejaculate)?

If YES, you MAY have a very low risk of pregnancy or of Sexually Transmitted Infections.


If a condom was not used for any kind of male/female sex, but another method of birth control was or is being used -- like the birth control pill, patch or ring, or like a cervical barrier -- to find your level of risk, refer to the effectiveness rating for your method of birth control in perfect or typical use. For the most part, however, when SOME reliable method of birth control has been used properly, no sexual activity is likely to pose more than a low or very low risk.

IF YOU WERE NOT FULLY CLOTHED, or, in other words, were wearing only your underwear/pantyhose/other minimal garment, or were naked, keep reading.

If you were less than fully clothed, or unclothed, but NOT having direct genitals-to-genitals skin contact, did any pre-ejaculatory fluid or semen get on or near the woman's pubic region, on her underwear or pantyhose, or any other minimal garment?

If YES, you MAY have a low risk of pregnancy. More significant is the risk of Sexually Transmitted Infections.If it has been less than 120 hours since your risk, you may obtain emergency contraception. If it has been greater than 10 days since your risk, see your health care provider as soon as possible for a pregnancy test and an STI screening.

If you have engaged in dry sex -- no actual vaginal entry, but genital contact -- and were unclothed, WITH direct genital contact, then you have a LOW to MODERATE risk of pregnancy. The amount of risk will vary based on the timing with your own fertility cycle, and also what kind of contact we're talking about: sometimes "dry" sex without clothing, with direct contact between penis and the vulva or vaginal opening, can wind up being a lot like intercourse. If it has been less than 120 hours since your risk, you may obtain emergency contraception. If it has been greater than 10 days since your risk, see your health care provider as soon as possible for a pregnancy test and an STI screening.
