Minami Hano is 36 years old this year. A housewife has been married for 10 years. A family of three, the husband of a company employee and the son of a student. "It always ends in the blink of an eye, so I started to learn about it (laughs)." One of the most concerning things is the time from insertion to ejaculation. "It seems like the average is 5 minutes and 30 seconds. My husband's is about 3 to 4 minutes." Minami was convinced. "The average sexual intercourse time is also short... Thinking back, my husband is increasingly unsatisfied. The same is true of the people I dated before marriage." Hope appears because I long for it. "Usually the positions are missionary and vice versa, so I want you to do a variety of positions, and I'm curious to see what it's actually like." !
