At what age do you go through puberty?
By Stephanie Pappas, LiveScience. Contrary to the reassuring catchphrase "size doesn't matter," penis size may matter in bed — but only for some women, and for certain types of orgasms. A new study finds that women who have frequent vaginal orgasms are more likely than other women to say they climax more easily with men with larger penises. Women who tend to prefer penile-vaginal intercourse over other types of sex also say the same, researchers reported online Sept.

Back to Sexual health. Puberty can be a confusing time, because your body and your feelings are changing as you grow up. Here are answers to some of the questions that boys often ask about their bodies. Puberty describes all the physical changes that children go through as they grow into adults. Most boys start to go through puberty when they're around 13 or 14 years old, but there's no right or wrong time. It might be sooner or it might be later, and this is normal.

Whether you are trying to get pregnant or avoiding pregnancy, the biology of sex remains an uncomfortable, misconstrued topic, encompassing various myths. Although everyone is aware of how fertilization of egg causes pregnancy, the question here arises- how do you know whether sperm went inside you? On orgasming, a man ejaculates semen through his penis which leads to cum in the vagina. Semen contains millions of sperm cells that swim through the vagina and into the fallopian tube. So, during unprotected sex, if the penis enters the vagina and a man ejaculation, it is sure that the sperm has entered inside the woman's body. As sperm entering a woman's vagina can cause unwanted pregnancies, numerous women prefer to indulge in self sex as well. You can practice this by learning how to use a vibrator as well. Sexual intercourse between a man and a woman occurs when an erect penis enters a vagina with in-and-out motions. However, that's not all.
