This area at the base of the penis can be stimulated in various ways. By sucking. Through the penis' "little tube" (the urethra). It is possible to stimulate the L-spot by making an inhalation.
Our female ancestors naturally moved their vaginal muscles by producing an inhalation during sex. This explains why the L-spot is located where it is. Today few women are aware of their vaginal muscles and so it's difficult that the L-spot is stimulated normally during sexual intercourse.
The same effect can however be attained through oral sex. By sucking rhythmically (that is, sucking and then stopping, repeating the act in rapid succession) you can very well stimulate the L-spot. In fact, it's possible to make a man reach orgasm just by sucking him, placing the lips on the tip of the penis, as if it were a straw, without otherwise touching it.
Obviously, it's not the same for everyone and the sucking should not be too forceful. Be careful not to overdo it, it can be irritating. It should then be said that it would be good to continue the inhalation even during ejaculation. In fact, the orgasm from L-spot is longer than the orgasm from the stimulation of the sensitive spot under the glans (the male clitoris). It would be a pity interrupting pleasure by stimulating with a gentle and deep massage the area of the perineum, between the joining of the scrotum (the sack that contains the testicles) and the anus.
It's possible to stimulate the L-spot through anal stimulation. This explains, among other things, why homosexuals can reach orgasm through anal penetration or why many men enjoy being penetrated with a finger during sexual intercourse. Up to a while ago, it was assumed it was a capacity for the prostrate gland. This is what Lada, Perry and Whipple wrote in their book "The G-spot":
"In fact, one of the reasons why some men feel pleasure in homosexual sex is that often in a union of this type, the prostrate gland is stimulated more easily than in heterosexual sex."
Doctor Leonelli however has demonstrated that things stand otherwise. In fact, how can this type of deep orgasm be reached with the method of inhalation and perineal massage if the centre is located in the prostate, which is reachable only through the anal route. If you have some doubts on the subject, try the experiment of sucking the tip of the penis and you will verify the point. Sometimes it is difficult to prove an obvious biological truth when in front of you have a sexologist who was seventeen years old the last time he had a close encounter with sex and didn't like it. A minimum of experience as part of one's qualifications should be considered essential in this profession.
