My husband struggles to get properly excited and thus we are facing problems in sexual life. Help us please. He is overall healthy.

Need further info. How old is your husband? as you get older, testosterone levels drop, and replacement is easy. Problem maintaining an erection? two medications for ED correct that problem. Under too much stress or anxiety to maintain libido? he or both of you may see a psychologist for counseling. If medical causes are excluded, you may wish to see a sex therapist.
