From condom usage to orgasm frequency, the largest sex survey since 1994 shows some interesting findings.

The results were mostly predictable, but there were a few surprising curveballs that caused our eyebrows to raise. Here they are outlined below.

1.) Homosexual sex: It’s not just drunk college girls having some same sex fun: Roughly 6 percent of male participants identified themselves as gay but 12 percent had received oral sex from a man, 11 percent performed oral sex, and 8 percent had anal sex with a male partner. In the same vein, a good 15-16 percent of women experimented with one another while only 1 percent consider themselves lesbians. While we’re on the subject of homosexual experimentation, same gender sex peaks for women in the 20-24 age group and then tapers off; meanwhile, same sex activity for men begins to gain steam in the 16-18 year range and stays consistent up until middle age.

2.) Condom use: According to the NSSHB’s study findings, only 1 of 4 acts of vaginal intercourse are condom protected. However, the survey also revealed that more blacks and Hispanics are consistent condom users in comparison with whites. Overall condom usage declines with age–perhaps due to monogamy and marriage–but mercifully, the study revealed that those in a casual sexual relationship are twice as likely to use condoms than those in relationships.

3.) Alcohol and sex: Say what you will about these crazy kids today, but researchers found that men and women aged 50-59 were the most likely age group to report drinking alcohol or smoking marijuana before their last sexual encounter. Could this be the second wave of craziness once the nest is empty?

4.) Orgasms: This one was no shocker but is always disheartening to see, 85 percent of all men polled said they had an orgasm during their last sexual encounter. In contrast, only 64 percent of women could say the same. Also not surprising, women are more likely to climax if there’s a mixture of oral and vaginal sex. Men, on the flipside, only need vaginal sex in order to reach the big O. And, proving the stereotype, 85 percent of all men polled believed their partner had in fact orgasmed.

5.) Masturbation: Across the age groups, men top women in reporting having masturbated alone within the past year. The 25-29 age range seems to be the most active solo masturbation period for both men and women, with 84 and 72 percent reporting having done so. The lowe
