Unlikely, but I recommend that you speak with a doctor
. First, it is difficult to safely engage in sexual intercourse with multiple partners by definition. If this is the lifestyle that you choose to live, then there are things that you can do to help be safe. While barrier methods of contraception
offer enhanced protection against some of the common sexually transmitted diseases and can help to prevent pregnancy, they are not fool proof, and can result in unwanted side effects. With regards to the symptoms that your wife is describing, it is important to understand if there is anything different in your sexual activity such as using different methods of contraception (eg, a different brand of condoms). While that is a possibility, another likely possibility is that your wife could be having some difficulty with creating the lubrication necessary when she is sexually active with you. If anything is impairing that lubrication, then there is the possibility that chaffing could arise, and this can be uncomfortable. There are lubricants that can be helpful in these situations, and may help to relieve her symptoms. Despite that fact, it is important to speak with your doctor to make sure that there is no other cause. Also, regular testing for STDs will be important. Please speak with your doctor and suggest that your wife speak with hers as needed.
