Despite using lots of lubricant my hubby is still unable to penetrate into my vagina and slip out very often. I also felt pain during the process. Any advice?

Hormonal changes can cause vaginal dryness, especially a dip in estrogen which happens after childbirth, during breastfeeding and when you reach menopause. The vagina needs estrogen so talk toa doctor about estrogen therapy. Not enough arousal also causes pain during sex since the vagina is not titillated enough. Try oral sex or hand stimulation until you come? That should help, I hope.

Mb try after bathing? When whole body is relax and wet but not dry. If not try in shower, slowly try a few times more 1st to get the mood and feel.

There seems to be a huge hormonal change in your body. Try to get more foreplay in action. This will help you to get lubricanted easily
