The perfect sex is only in books. And in the movies, where all men have sculpted muscles and women seem to be specimens on a permanent diet. In reality, intimate moments can be sprinkled with memorable blunders, good enough to be turned into jokes.
Specialists, that is to say those individuals with professional opinions, claim that everybody is bisexual, whether they realize it and peacefully accept their orientation, or if they live in constant denial.
If the mankind feels or not attraction to both genders is less important. The fact is that a non-negligible part of the population falls within this category. A category of people excited both by men and women (which considerably lowers the risk of spending their evenings alone, on the couch, watching adult channels). In other words... more opportunities.
What else could be said about sex in addition to the tons of information that is already circulating fast as a high-speed train? Fortunately (for all of us), given that the subject is a vast and inexhaustible one, the novelties continue to emerge, bringing to light new unusual aspects related to human sexuality and its always exciting challenges.
