Is there any health risks with oral sex ?

Yeah don't bite or it will bite back.

Of course, there's always the risk of STD's.
Absolutely. My husband explains to me that when being with a new woman you must look it over before you lick it. Of course you can't just stare at it but make it an intimate thing so she doesn't feel nervous. Look for anything like bumps, sores, foul smell, weird discharge (green,clumpy). If all that looks good chances are you are good to go. However, the risk after all that checking is that they may have herpes but not have an outbreak at the time, they may be hiv positive or may have a yeast infection. All risks from the male point of view. For women we have to check you guys out just as good and look for all the same stuff and still have all the same risks. However, in a healthy relationship the greatest risk you'll have to deal with is becoming so effective in oral sex that you make her *** so hard you're drowning in her juices or that you're so good at it she'll want it so often that your jaw experiences pain and locking up from going at it so long. This is the problem my husband has. While it is an enjoyable problem he is amazing at what he does and I could let him go for hours if he or I could stand it. Of course you'll want to make sure to not have a cold sore or any other mouth sores before oral sex. Enjoy it all, do it all, just make sure your partner wants it. Never force it and never never never stay on the cl*t long, love the hole and all around the lips, but love the hole most.
