I think society expects that males will “sow their oats,” and females will be more conservative, which makes them more desirable as marriage partners. Of course, our world has become liberal and accepting of the hedonistic, so this generalization doesn’t have much validity nowadays. Sluts of all stripes marry and children, and nobody blinks an eye. At least, in the Western “Christian” world. However, all cultures allow men to act “slutty.” It is expected of them.
There is always the risk of STDs with slutty behavior. Everyone, ESPECIALLY SLUTS, should be vaccinated against HPV, for example and use condoms.
HPV vaccine is approved by FDA and is recommended by CDC for both males and females. It is routinely given at 11 or 12 years of age, but it may be given beginning at age 9 years through age 26 years.
Most adolescents 9 through 14 years of age should get HPV vaccine as a two-dose series with the doses separated by 6-12 months. People who start HPV vaccination at 15 years of age and older should get the vaccine as a three-dose series with the second dose given 1-2 months after the first dose and the third dose given 6 months after the first dose. There are several exceptions to these age recommendations. Your health care provider can give you more information.
