Vaginal wetness issues are common among post-menopausal women as well as women who are breastfeeding, due to low levels of estrogen which can cause problems with vaginal dryness throughout the day and not just during sex. Certain medications can also make it more difficult to produce sufficient vaginal lubrication for sex.
One of the health-related problems with sharing sex toys is that it is not known how long certain bacteria or viruses can survive in sex toy materials. That means that sharing sex toys can result in sharing infections.
Even though research suggests that more than half of women and nearly half of men have used vibrators, there has been strikingly little research related to the toxicity of sex toy materials. However, the little that we do know suggests that toys made of glass, medical grade silicone or hard plastics are likely among the least toxic.
My girlfriend’s vagina gets very dry during intercourse. I have to use a lot of lubricant in order to have sex with her and then it get dries again after 10 minutes. She is not taking any medication or birth pill. Sometime it is so dry that it damages the condom. In foreplay she is wet for a few minutes, but then she gets dry when we have sex.
