penis

Condoms are designed and tested -- each and every one of them, by every manufacturer -- to be able to withstand ejaculation (what you're calling "erupting") as well as to contain a single ejaculation: the amount of semen a person with a penis emits when they ejaculate. They test them by blowing...

Here's a quick roundup for you. Oral sex is sexual activity between partners in which someone's genitals -- penis, testicles, vulva (vagina, clitoris, labia) or anus -- are being stimulated by someone else's mouth, lips or tongue. Names for some common oral sex activities are cunnilingus -- giving a...

Throw a rock at any sex education site or service, ask what the most common question we get is from men and we'll all tell you that it's about penis size. We don't imagine with this piece we'll never get asked again, but we're hoping these answers get you guys better filled in so you can feel good about yourselves, your penises and whatever you do (or don't) do with them.

Here's the kicker: there's nothing we can do or know which will guarantee that a partner will enjoy something we do. Nothing. One facet of readiness for partnered sex has to do with being able to accept that and be okay with it. Another part is knowing that no matter what we do, there are probably...

Honestly? The biggest fantasy driving the bus here is that the length of time your erection lasts has much to do with your partner's pleasure (or yours, to some degree) at all. That isn't to say that you won't likely have sex partners -- some, plenty, even all of them -- who don't enjoy sex that...

From a reproductive standpoint, the purpose of an erection is to allow for insertion of the penis into the vaginal canal and ejaculation. Once the erection has served that purpose, there is no reason for it to continue. Also, typically after ejaculation or orgasm, sexual arousal wans. As that...

How familiar are you with the changes to your vulva or the rest of your body when you get sexually aroused? I ask this, because I'm willing to bet that there have been times, for you, when you're with a partner you're attracted to, and who you want to be with, but find that your clitoris is not as...

People tend to forget that young men often may not even be at the stage in their sexual development where erections happen often or easily or where they can yet ejaculate. Some guys are just starting puberty at 14 or 15. Your boyfriend simply may not be at this stage in his development yet. But...

Are you ticklish? Or do you know people who are ticklish? I'm really really ticklish on my knees. Touch my knees and I absolutely go crazy! My partner, however, is totally unmoved by knee contact. In fact, he's only really ticklish on his feet and elbows. My sister's tummy is her most ticklish spot...

There is no one sexual activity, nor any one way to engage in any one sexual activity, which will guarantee orgasm or ejaculation for any given person, or for any given person every time. Plenty of people with penises will reach orgasm and ejaculate with oral sex, though many of those people won't...
