Doctor's View About Sex For Healthy Person:
Men are often in the mood to have sex in the morning because they may wake up aroused due to nocturnal penile tumescence, which causes men without erectile dysfunction to experience between three to five erections as he sleeps. Also, men's testosterone levels are highest in the morning.
"If he has some kind of erectile activity in the morning, he should rejoice that he has an erection!" sex expert Dr. Ruth Westheimer says. "We women were taught that it has to be dark, that the stars have to be twinkling and that it has to be in the evening in order to be romantic. I'm saying, nonsense! Close the shutters, make it dark in the room if that's what you want. Make sure you adjust to what both of you like. SEX IS VERY IMPORTANCE FOR EVERY ONE YOU SHOULD DO SEX MINIMUM ONE TIME IN A MONTH.
"People are not Siamese twins," Dr. Ruth continues. "They don't want to have sex, or the same amount of sex, at the same time. The important thing is that that couple, for the good of the relationship, adjusts to it. Also, what they can do is [have sex] one week at night, and one week in the morning. What's the big deal? Be a little bit flexible."
