Hello, and I am pleased to help, use of my answers are for educational purposes only.
This might be due to vaginal atrophy due to decrease estrogen from being in menopause.
So, you might benefit from some Estradiol (premarin) cream.
Also, you might benefit from an over the counter product called Replens.
Yes, I mentioned Replens as this can help too.
And, with burning during ejaculation, you might also consider using RepHresh - as this could also be a pH problem in your vagina.
I would also recommend a visit to your ob/gyn if you have not had a pelvic exam in over a year.
I hope this helps, Please click on ACCEPT, thank you for your question.
