Let me share with you two of the most common myths about the female orgasm
Myth 1: Women can reach orgasm more easily if her partner has a large penis.
Men who have worried for eons about the size of their penis can relax. The truth is that size really doesn't matter all that much. Since only the first two inches of a woman's vagina are sensitive to stimulation, anything over that amount is kind of useless during intercourse, at least from the woman's physical perspective. In fact, when men are overly concerned with the size of their penis and whether it's sufficient, their minds aren't focused on pleasuring their partner and that is no way to experience female orgasm. A survey done by the Kinsey Institute found that the average size of an erect penis measured from the tip to where it connects with the rest of the body is 6.16 inches (15.65 centimeters) in length. The girth of an erect penis is 4.84 inches (12.29 centimeters) on average. That same Kinsey study found that less than 2% of men have penises over 8 inches.
Myth 2: If a woman does not have an orgasm, she did not enjoy the sex.
Most women have had the experience of being asked by their partner during sex if they are going to "get off." This myth is the reason for that question. The majority of men believe that sex without an orgasm is not pleasurable for a woman, but that's not true. First of all, even though orgasms are a wonderful part of the sexual experience, there is more involved than that. For couples, sex is generally a physical expression of love and closeness. Many women report enjoying this part of the experience immensely even when it is not followed by an orgasm. Second, just because there's no climax that doesn't mean the rest of the experience didn't feel good. An orgasm is an intense pleasurable feeling but it is not the sole source of sexual pleasure for a woman. Just as men enjoy the actual act of intercourse, so do women. Third, when men ask about whether or not a woman is going to climax, he is putting pressure on her to deliver and this generally leads to faking orgasms which actually detracts from her experience and could detract from his as well if he discovers the truth. Furthermore, when a partner is truly in tune with a woman's body, they don't have to ask that question: the signs of a building orgasm are unmistakable and cannot be faked.
So, relax, chill out and enjoy!
