My girlfriend and I were having sex in the shower, not for too long at all, we were probably having sex for 5 minutes and got out and finished up. The next day, she said she felt irritated down there, a slight stinging and such. Her lips were slightly red and it was around 3 days before she was up for sex again. Is there something in normal hair shampoo that makes it a bad thing for vaginas? is it the water? Any ideas?
You didn't directly say if you used shampoo as a lubricant, or exactly how much was used between you and her down there if any, but if you guys did use shampoo as a lube, then yes the chemicals in the shampoo can REALLY cause stinging, pain & redness inside her due to the chemicals throwing off the skin balance of ph and alkalines. Each shampoo is different, but the chemicals in them and the thin skin of the inner vagina are not a good mix and once you mix up the alkaline balance you can get irritation quickly. NO worries though, just get a small bottle of water based lube and keep that near the shower it will work better last longer and best of all will not cause the pain down there for her which is better for both of you in the long run. JUST BE CAREFUL a SMALL dab is ALL you need and if you use more than needed it can make the shower floor VERY slippery.
