From promises of an increased libido to a larger penis, natural male enhancement pills lay claim to them all. These herbal dietary supplements, which even purport to treat erectile dysfunction, may seem like a less expensive at-home treatment to address your most private concerns. However, MayoClinic.com and the Center for Science in the Public Interest, or CSPI, warn that the effects of natural male enhancement pills are likely less than transitory -- in fact, they may not work at all.

Treating decreased sexual desire and arousal in women is tricky. Viagra, the trade name for the oral drug sildenafil, is a prescription medication men can take that makes it physically possible for them to obtain and maintain an erection. However, medical experts agree: When used to enhance your sex life, Viagra works only for men.

Contraceptive foam is one form of spermicide which, along with creams, gels and suppositories, kills sperm before it reaches your uterus. Contraceptive foam has some side effects that can affect men -- and women, too. But the biggest downside of using contraceptive foam on its own is that it doesn't protect your partner from STDs, HIV or an unplanned pregnancy.

While erectile dysfunction is not something that physically impacts women, those partnered with an erectile dysfunction sufferer will certainly feel the effects. If your partner is struggling with erectile dysfunction, you can play a part in helping him come to terms with and treat the disorder. By learning about erectile dysfunction, you can prepare to modify your relationship to accommodate this challenge.

Men have the option of using prescription drugs to treat erectile dysfunction, making it possible for them to perform in the bedroom. However, drugs to boost female sex drive are so scant as to be nonexistent. According to MayoClinic.com, the reason for this is that a woman's low libido cannot be cured with a pill. Your desire to have sex depends on many different things, such as your physical and emotional health -- and the strength of your relationship with a spouse or partner.

If the thought of catching up with your nighttime television soaps is more appealing than an amorous encounter with your partner, this might be perfectly normal. MayoClinic.com says it's common for your sexual desires to wax and wane during the course of your lifetime. However, lows that recur or linger can be caused by one or more factors. If your sex drive is nil, various things could be going on in your body -- as well as in your life. It's easy to overlook the obvious ways your libido became suppressed.

The kids, the phone, the daily grind and all the tensions that build up -- it's no wonder that when you fall into bed at the end of the day, sex and intimacy take a back seat to sleep. If your love life is suffering from a loss of libido -- yours or your partner's -- herbs that nudge your sex drive into overdrive may provide the spark you need. Remember to consult with your health care provider before you begin taking any herbs.

If your sex life has become lackluster due to infertility or sexual energy problems, you and your partner may both feel frustrated and even less confident than usual. While a number of medications can potentially help increase fertility, some natural remedies can help boost sexual virility, notes both MayoClinic.com and the University of Maryland Medical Center. But before giving your man any herbs or supplements, check with his doctor if he is taking any type of medication or has a preexisting health condition such as high blood pressure.

Remember that sex is for you and your enjoyment. Rather than thinking about it as one more chore on your to-do list or one more thing someone wants from you, think of it as your time!

Sometimes, even healthy and fertile women and men experience unexpectedly short stints of sexual activity or just aren't in the mood for love making, according to both MayoClinic.com and Discovery Health. Coming up with ways to last longer during sex can be fun and productive, especially when trying to create a baby. But keep in mind that some types of sexual problems need a doctor's attention and that taking supplements while pregnant or using another type of medication is not a good idea.
