let me just say little for no. 4.
To be sincere, man can not sertisfy ladies. If a guy is promising a lady I will do everything for you it's a big lie. Because you can't just sertisfy ladies, even man is doing the best for his wife, the man haven't done anything that is what woman says. So we can sertisfy each others but if there is true love..... I mean real love.... We sertisfy.
