You can have an enjoyable sex life, despite postpartum vaginal dryness. The following are tips for enhancing your experience:
Use a lubricant when you’re having sex. If your partner uses a condom, avoid petroleum-based lubricants, which can damage condoms.
Talk to your doctor about using an estrogen vaginal cream, like conjugated estrogens (Premarin) or estradiol (Estrace).
You may also want to try a vaginal moisturizer, which is applied every few days.
Drink water. Keep your body well hydrated.
Avoid douches and personal hygiene sprays, which can irritate sensitive vaginal tissues.
Talk with your partner about your concerns.
Increase foreplay and try different techniques and positions.
