Sex Toy Dangers
When used correctly, sex toys can enhance the bedroom experience. But there are potential risks that come with the pleasure they provide.

Cleanliness is essential because many adult novelties can carry sexually transmitted diseases and cause other infections. "When it comes to certain sex toy devices," ER physician Dr. Travis Stork says, "Planned Parenthood and other organizations recommend using condoms on your sex toys to keep them clean. It's really important."

Knowing what your device is made out of is important as well. Many toys are made from plastics, such as PVCs, which contain phthalates. "[Phthalates] are known to, at times, to be hormone disrupters, can cause kidney, liver and other damage in too great of a quantity," Dr. Travis says. "There are some people making sex toys now that are moving away from using these types of plastics because of the theoretical concerns."

"Also, none of these should be used directly on the clitoris," Dr. Ruth says. "The clitoris is too sensitive. It should be used around the area of the clitoris in order to really feel sexually aroused and to have an orgasm."

Faking the Big O

According to a study, 67 percent of women and 30 percent of men admit to faking an orgasm during intercourse. The Doctors and Dr. Ruth reveal the most common reasons people fake sexual climax and how to tell if your partner's is authentic.

"[Sex toys] can actually be dangerous if you don't use them correctly," Dr. Travis says. "You really do need to know what you're doing with these things."

Q: Will too much self-pleasuring cause damage?

Semen Consistency

Adam, 26, has noticed a change in the consistency of his semen. The Doctors demonstrate what the different consistencies mean, and when you should see a doctor.

Plastic surgeon Dr. Andrew Ordon: "Too much pressure, constant vibration all the time, could lead to damage to the skin and damage to the nerves. [Too much] can become like an obsessive-compulsive disorder, that all you think about is self-pleasuring. But it is healthy in the right amount."

Q: Can a man ever run out of sperm?

Dr. Lisa: "He shouldn't if he's good and healthy. He can produce 50,000 sperm a minute. As long as everything is working, you shouldn't run out."

Dr. Travis explains that the body manufactures sperm throughout the day to keep the sperm healthy. "It's actually good to ejaculate, it's healthy," he says. "Unlike women, who have a certain number of eggs in their lifetime, men have plenty of sperm to go around. And then some."

Q: At what age can a boy get a girl pregnant?

Dr. Travis: "[At] puberty. It's no specific age, but usually around [age] 10 to 14. Puberty takes years to take place, and the voice deepens, you'll start to see facial hair, there's going to be testicular growth."

Dr. Ruth is bothered by the question: "I do not want boys to get women or girls pregnant. I want them to wait, and the woman to wait, until they know what they are doing and use contraception if they have sex and don't want to be parents. The question, when can a boy get a girl pregnant, is worrisome.

Sync Your Sex Clock
Natasha says that her boyfriend wants to have sex in the morning while she enjoys it at night. She asks how they can sync their sex clocks.

Men are often in the mood to have sex in the morning because they may wake up aroused due to nocturnal penile tumescence, which causes men without erectile dysfunction to experience between three to five erections as he sleeps. Also, men's testosterone levels are highest in the morning.

"If he has some kind of erectile activity in the morning, he should rejoice that he has an erection!" Dr. Ruth says. "We women were taught that it has to be dark, that the stars have to be twinkling and that it has to be in the evening in order to be romantic. I'm saying, nonsense! Close the shutters, make it dark in the room if that's what you want. Make sure you adjust to what both of you like.

"People are not Siamese twins," Dr. Ruth continues. "They don't want to have sex, or the same amount of sex, at the same time. The important thing is that that couple, for the good of the relationship, adjusts to it. Also, what they can do is [have sex] one week at night, and one week in the morning. What's the big deal? Be a little bit flexible."

Sex Surrogate
A sex surrogate is someone who engages in sexual activity with a client for teaching, therapeutic, psychological or other reasons. But is it safe for your relationship?

"First of all, it's illegal," Dr. Ruth says. "But it's not only that. It's dangerous. Number one, sexually transmitted diseases, because if [he or she] is a surrogate for that couple, he or she is going to be, two nights later, a surrogate with somebody else.

"Also, to bring in a third person, even if that third person would not get paid, even if it's somebody who does it for fun, or even if it's two couples who swing for fun, it is dangerous psychologically speaking, because one or the other are going to fall in love," Dr. Ruth continues. "I would say surrogates, in your brain, yes. In your fantasies, yes, but not in your bed. It's a no-no in my book."

If you are having sexual problems in your relationship, Dr. Ruth suggests seeing a sex therapist.
