Quiz: Sexual Fact or Fiction?

Sexually transmitted infections can be passed not just through penile-vaginal intercourse, but by oral sex or anal sex due to the exchanging of bodily fluids. Certain STIs, such as genital warts and herpes may be transmitted through skin to skin contact with infected genitals.

A female can get pregnant any time she has unprotected sex with a male, whether it's the first time or not. Once ovulation occurs, pregnancy can happen, even in young girls who have not yet gotten their periods.

Penises come in a variety of sizes and shapes. The average length of an erect penis is between 5.1 and 5.5 inches (12.95-13.97 cm). While many men wish they were larger, the size of a man's penis does not affect the amount of pleasure he feels, and it has minimal effect on the amount of pleasure for his partner.

It is impossible to tell how much sex or how many partners a person has had by how loose or tight their vagina appears. The vagina is a muscle that expands and contracts. When a person is aroused, the walls of the vagina soften and lengthen during arousal, which makes insertion easier. The walls of the vagina may contract if a person is anxious or insufficiently aroused, making insertion difficult.

Sex should feel good. If it doesn't, it may be a sign something is wrong. According to the American College of Obstetricians and Gynecologists, nearly 75% of women experience pain during intercourse at some point in their lives. Causes of pain during intercourse include vaginal infections, vulvodynia, vaginismus, hormonal changes, endometriosis, ovarian cysts, some skin disorders, childbirth, low sexual desire, or insufficient lubrication due to lack of arousal. Talk to your doctor if you experience pain during intercourse.

In the past, "virginity" was used to label a heterosexual person, particularly a female, who had not had vaginal intercourse.

But sex and the "first time" means something different and personal to everyone of all sexual orientations and genders. Today, individuals can decide what virginity means to them.

Pregnancy is possible even if a man pulls out before ejaculating. Males discharge bodily fluids before ejaculation and women produce vaginal fluids during arousal, and the exchange of bodily fluids could result in pregnancy. Sexually transmitted infections (STIs) can also occur even if a male pulls out before ejaculation.

There is an image of men that they are always ready and willing to have sex, and that men always have a higher sex drive than women, but it's not true. Even men who like to have sex frequently can have times they just don't feel like engaging in sexual activity. To believe that a man will always want sex puts added pressure on men to perform, even when they don't want to. Men must also learn to say no when they are not in the mood.

Sexually transmitted infections (STIs) are passed from person to person through body fluids. Bacteria and viruses that cause STIs cannot survive outside the body, and it is next to impossible to contract one by sitting on public toilet seats.

The bottom line with pornography is the bottom line: it's a business and the goal is to make money. Pornography usually shows fantasy scenarios that can differ greatly from how people have sex in the real world. The goal of sex in real life is usually about intimacy, respect, and consent, which is not present in some pornography.
