Dr. Booth Enticenhymen is a resident sexpert of the famous Hoppenflotzen Sexual Dysfunction Clinic in Sizetmaters, Germany. Dr. Booth, as his patients call him, was born in Fargo, North Dakota on January 1, 1976. He received his medical degree in urology from the Milïken Böne University of Medicine in Greifswald, Germany in 1999. Because of his excellent bedside manner and good looks, he was named #1 in Pleasure Magazine's 2005 "Top Cocks in Docs."

Dear Dr. Booth,
I am a twenty-two year old woman who masturbates frequently, and by frequently I mean 4-5 times a day. I love getting myself off, because 1) I can do it very quickly with no muss or fuss, and 2) because it's a lot less work then having sex with someone. I know, you are wondering if I am so freaking happy with the arrangement, then what's the problem. Well, the problem is, I am worried that I will never be satisfied with a partner. I have a boyfriend whom I've been seeing now for three months. I can come and come again when I'm alone, but haven't been able to have an orgasm while having sex with him, not even during oral sex! I love him, but I think I've broken myself for any one other than me. Can you help?

Thanks,

Dear Monster,
While a little unusual, I can assure you that you are not broken for any one else but yourself. What you have done is discover exactly what turns you on and what doesn't. All you have to do is work it into your sexual routine with your partner. For example: If you use a vibrator for clitoral stimulation while masturbating, use a vibrator in the same way while having intercourse or even oral sex. If you incorporate the techniques that fire you up while you're alone, into your sex life with your partner, I believe you will find every thing in perfect working order.

Dear Doc B.,
I am having a major serious problem. I've been married for three years and still enjoy an incredible sex life with my husband, but l keep getting bladder infections after vigorous, well, you know. The whole thing has become a total turn off for me. So, I burn and itch when I pee, I'm on an antibiotic (which has given me a yeast infection -- hence the itching), and my husband can't understand why I haven't been in the mood! How can I keep from getting this again?

Any advice?

Dear Burning,
It's hard for men to understand female problems, in particular period pain, yeast infections, and (believe it or not) urinary tract infections (UTI's). Men just rarely get them. It has to do with anatomy (and no, this has nothing to do with penis envy). A woman's urethra (the tube you urinate from) is about an inch long, while men have urethras that are about 8 inches. Because of this, when a woman's urethra is introduced to bacteria it doesn't have to travel very far before it reaches the bladder.

The good news is that there are several things you can do to help prevent these infections from occurring in the future: of course, always practice good hygiene, make certain you urinate at least 15 minutes after intercourse, eat cranberries and blueberries which contain tannin (an astringent found in certain plants) making it difficult for bacteria to adhere to the bladder walls, take showers or urinate soon after bathing, and always urinate when the urge arises. Now, even with taking all these precautions, a UTI may reoccur. If for some reason you have more than 3 UTI's in a short period of time, you may ask your doctor to put you on prophylaxis antibiotics (to be used before intercourse and up to three days after). Good luck!

Dear Doctor Booth,
I'm a forty-year-old man, and I've been married for 15 years. The other night while I was having sex with my wife, she put her finger in my butt. I'm really embarrassed to admit that it felt really good. I had a zinger of an orgasm like I haven't had in a very long time. The problem is I was so ashamed afterwards that I got angry with her for doing it to me. We haven't talked about it since. I've been raised to believe that your butt is where things go out, not come in, but I can't stop thinking about how good it felt. I've always associated this kind of stuff with being gay, now I am worried. Am I a pervert?

Dear Fickle,
First of all, let me say that homosexuality is not a perversion, merely another form of sexuality. But, I get the feeling that it isn't men you are interested in, so no worries there. Anal stimulation is one of the last taboos society struggles to overcome. It is perfectly normal to enjoy anal play. The anus is richly bundled with nerve endings that are closely tied to your genitals. Just because you enjoy being touched there, or even penetrated does not make you a pervert.

Many heterosexual men enjoy penetration with a finger, or even a dildo while masturbating or having intercourse with their partner. As long as it doesn't hurt, it is a perfectly safe and healthy eroticism. You need to talk with your wife, because it sounds like in her attempt to spice things up, she inadvertently made you uncomfortable. Once she finds out that you enjoyed the stimulation, chances are your sex life is only going to get more adventurous! Go slow, be hygienic (clean your anus with soap and water before sex), use a water-based lubricant for deeper penetrations, and have a great time.

Thank you readers for your great questions! And thanks OCO for allowing me to guest on your column. From Germany, this is Dr. Booth Enticenhymen wishing you lots of healthy and pleasurable sex.
