Can swallowing semen affect a girls waste output? I had been noticing some pretty potent pee lately, but couldnt make a connection between any new foods or environmental concerns. Then I noticed a corelation between swallowing and the strong smell. A day after, bingo. Am I nuts?

Everything you put into your body has to come out at some point. As far as swallowing is concerned I’ve never heard it could have an effect on your urine but I know other foods like asparagus will make your urine smell different and not drinking enough fluids (dehydration) will also make your urine more potent. Any sort of foul smell that is not directly effected by your diet can be a sign of an infection, in this case most likely a urinary tract infection or UTI.My advice for you is to make an appointment to see a doctor as soon as possible. If it is in fact a UTI as it sounds make sure you practice proper personal hygiene including but not limited to urinating immediately after intercourse, always wipe from front to back, washing the skin around and between the rectum and vagina daily. Washing before and after sexual intercourse may also decrease your risk of UTIs. Make sure your partner’s genitals or sex toys are properly cleaned before and after sex as well. Drinking plenty of fluids can also help flush bacteria out of the urinary tract. Emptying your bladder as soon as you get the urge to urinate will also help decrease your risk of bladder or urinary tract. Do not wear tight fitting clothing around the genitals and you should wear panties with a cotton crotch that allows to absorb moisture. Other materials can trap moisture which creates an ideal environment for bacteria. While UTIs are common and can be painful, they are usually easy to treat once properly diagnosed so seeing a doctor as soon as possible is in your best interest as untreated UTIs can lead to more serious complications. It is possible that something else might be going on that’s causing infection or irritation. You might consider switching to a more organic and natural lubricant, which will reduce friction and irritation. Also make sure you throughly clean any sex toys before and after use even those that are not used internally.Other secretions (vaginal secretions, cum, etc) taste and smell the way they do because of health, habits, and diet. To make your secretions taste better cut alcohol, caffeine, recreational drugs and nicotine out of your lifestyle. Drink more water. Eat lots of fruits and vegetables but avoid certain veggies including cabbage, cauliflower, broccoli, and asparagus. They say vegetarians taste better for a reason. Also avoid red meat, dairy, milk, cheeses and heavy spices. Don’t buy products that say they will make you taste better. They don’t work. If you have followed these guidelines and follow proper hygiene you should go see a doctor as the foul smell could be a sign of an infection.

As far as swallowing is concerned: it is an exchange of bodily fluids which presents many risks. It is not necessary and is a personal decision. If you choose to swallow it’s generally around a teaspoon or so of fluid and only about 6 calories. It’s not high in protein or any of those other myths you have heard about swallowing a guy’s cum. Some dude just made that up because he wanted more girls to suck his cock and swallow. If swallowing is not your thing or you are just doing it to please your partner here are some suggestions for you. Ask your partner to let you know when they are about to cum. Allow them to signal you beforehand with a pinch on the shoulder or some other non-verbal cue. Let your partner know you don’t want to swallow. Use a flavored condom that way your partner can cum and there is no need to stop or swallow and there is less mess to clean up. If you don’t want to stop you can simply allow fluid to seep out of your mouth slowly while your partner is cumming. It can get messy so you might want to keep a towel handy. You can also offer an alternative I won’t swallow but… you can cum on my breasts/ass/etc.

Something else to think about: unprotected oral sex can lead to gonorrhea, chlamydia and other infections in the throat as well as things like HPV (Human papillomavirus) or Herpes which are transmitted via skin to skin contact. HPV in the throat has recently exceeded tobacco as the leading cause of throat cancer in the United States. Condoms and Dental Dams sound a whole lot sexier now don’t they?

This is a little outside our area of expertise, but we did some research and learned that there are a number of things that can affect the odor of urine. The main causes are diet (things like asparagus, onions, garlic and spicy foods.) Birth control pills can also create a change. If you are having vaginal intercourse as well as oral sex, you may be irritating your urethra a little. The rubbing of the penis can introduce a little bacteria into the canal, and a low grade bacterial imbalance can change the smells you are accustomed to. Sometimes, in the heat of a new romance, you can actually forget to eat regularly. Then ketosis kicks in, and the smell of urine and breath can change, and not in a good way. Our advice: When in the throes of sexual passion, keep a bottle of water handy and hydrate, hydrate, hydrate. It should take care of that morning after shift in how your pee smells. It will also help keep your breath fresh and keep your skin healthy. If this does not help, then you should see your physician, as unpleasant urine odors can be a sign of more serious health issues.
