I need help ladies. I’ve never had a problem with getting wet down there during sex or before but after giving birth so early I feel like nothing is the same down there 😢😩 and I’ve been using the preseed lubricant. I also have cervical cancer & a short cervix so that’s one of problems. Is there any tips or ideas you ladies can help with?
