The man in my life and I (heterosexual, monogamous for 13 years) are recently experiencing a burning sensation during sex. Both of us are experiencing the feeling of burning. It s only recently developed in the last 2 months. There is no pain after sex or while urinating. The only discomfort is the burning sensation we both feel during sex. I am peri-menopausal. We are in our mid to late 40 s. He likens the natural lubrication to an acidy burn. Occasional we will use astroglude as his skin on penis becomes sensitive and raw during sec. Also a new event for the past 4-5 months. Can you help?
