“For added stimulation, bring your legs together while the partner is thrusting, which will create a tight grip and insane pleasure for both of you,” says Nelson.

Sexual reproduction not only takes care of the need for replacement of individuals within a population but gives rise to populations better suited to survive under changing circumstances. In effect it is a kind of double assurance that the race or species will persist for an indefinite time. The great difference between the two types of reproduction is that individual organisms resulting from nonsexual reproduction have but a single parent and are essentially alike, whereas those resulting from sexual reproduction have two parents and are never exact replicas of either.

Because the life span of all individual forms of life, from microbes to man, is limited, the first concern of any particular population is to produce successors. This is reproduction, pure and simple. Among lower animals and plants it may be accomplished without involving eggs and sperm. Ferns, for example, shed millions of microscopic, nonsexual here spores, which are capable of growing into new plants if they settle in a suitable environment. Many higher plants also reproduce by nonsexual means. Bulbs bud off new bulbs from the side. Certain jellyfish, sea anemones, marine worms, and other lowly creatures bud off parts of the body during one season or another, each thereby giving rise to populations of new, though identical, individuals.

When we have sex, the physical signals felt by the body send signals through our nerves to the brain — which reacts by releasing chemicals that make us experience even more pleasure.

However, those who had sex more than three times a week had the same amount of IgA as those who had infrequent sex. The study suggests that anxiety and stress can possibly cancel out the positive effects of sex.

Don't sweat your size. Whether you're worried about stuffing a bra or about making your crotch look a little more full: don't.
