Ten minutes is actually a longer time, not a shorter one, for an erection to last once intercourse begins, especially for younger men. But even if he lasted a half hour, it's unlikely that you'd feel satisfied with intercourse alone or reach orgasm that way, since the majority of women do not. Your...

The difference is that PMS symptoms won't cause your pregnancy test to turn positive. Using symptoms to determine if you're pregnant is really unreliable. If you absolutely must know if you're pregnant, wait 10 to 14 days after the sexual encounter in question then take a pregnancy test using the...

There's nothing about having a menstrual period which makes it impossible or even difficult for someone to have any kind of sex. In fact, because there are extra fluids present, plenty of people find some kinds of sex -- like vaginal intercourse -- more pleasant during menses. People can also...

You can certainly do your best to help keep your immune system doing it's job to fight off anything you may have been exposed to, just by taking sound care of yourself: eating right, getting enough activity and rest, limiting or avoiding substances that can tax the immune system like caffeine...

You know, KY is really one of the lower quality lubricants out there. If you're using the jelly, it really isn't going to help much, but even their liquid lubes aren't as good as a lot of others in my opinion. An excellent lubricant is not only as good as "natural" lubricant, sometimes it's even...

It's very typical for condom use to contribute to longer lasting erections. Because they do reduce sensation somewhat -- especially if you're not putting a little lube inside, or using the thinnest condoms -- and because the ring at the bottom of a condom also constricts the base of the penis, that...
