8. You need an erection for sex:

Myth. The fact is that there is a lot more to sex than just penetration of a vagina with a penis. Several aspects of sex have more to do with the mental factor of the man and woman rather than the physical. So, even if you are struggling to have an erection, you can still have sex.

10. Water in the Jacuzzi can kill off sperm:

Myth. Birth control pills are formulated to prevent unplanned pregnancies without affecting the woman’s ability to get pregnant.

15. You have to be over 18 to buy condoms at the store:

Myth. Studies have shown that having sex the day before a sports competition doesn’t affect sexual performance (5). So, your performance in the field won’t be dampened because you performed in bed the night before.

23. Doubling up is safer than using a single condom:

Myth. Using two condoms, aka doubling up, can increase the risk of breakage since both condoms will create friction with each other. You are better off using a single condom.

28. Some sex positions reduce the risk of pregnancy:

Myth. The risk of pregnancy has nothing to do with the sex position you were in when you ejaculated. So long as the semen entered the vagina, there is a risk of fertilization. Just use a condom instead.

29. The pull-out method is 100% effective at preventing pregnancy:

Myth. Pulling out before ejaculation can significantly reduce your chance of pregnancy but it isn’t 100% (8). If your partner has missed per period, you may want to talk to a doctor for a pregnancy test.

Myth. Before anything else, if you or your partner think you may have an STD, get yourselves checked out first. There are some STDs (like HIV and Herpes) that aren’t curable but can be treated with meds. That said, most STDs are curable with little long-term effects.

35. The woman’s hymen will break/tear when she loses her virginity:

Myth. While some women experience their hymen tearing during their first sexual experience, many don’t. The hymen can be torn while riding a bike or using a tampon as well. She can also have sex without it tearing too.
