It’s wonderful that we live in a world that celebrates the
orgasm. Granted, there are still many people in the world that don’t understand
orgasms, realize their benefits, or seek to control them for negative reasons.
Having a national observation day gives us a chance to focus on this amazing
thing the body can do. Orgasms make us feel good, help us bond with partners,
release helpful hormones, reduces stress and contributes to our overall health.
We all experience orgasms in our own personal way; some quickly, some with lots
of effort, some multiple times, some with one big blow out. How does this sexy
bodily function work and what does it do for our bodies? Lets take a closer
look.
Body and Brain
An orgasm is an incredible feat of mind and body, the result
of physical stimulation and mental stimulation. Masters and Johnson considered
it the third of four stages in human sexual response. Our genitals have
sensitive nerve packed areas that are specifically designed for pleasure. Physical
stimulation of these areas starts a chain reaction while our minds are
processing what’s happening to cue different physical reactions. The groundwork
is laid during foreplay. As we start getting aroused the brain sends blood
flooding to our genitals. This increased blood flow causes our genitals to
swell and become more sensitive. Women have an increase in lubrication in the
vagina and vulva. Our breathing and heart rate increases. This process is
changing not only our bodies but changing what’s happening in our brains. We
shut down parts of our brain, mostly ones that regulate things like fear, worry
and planning. Our minds are only focused in the moments leading up to orgasm.
The hypothalamus releases hormones so we’re flooded with oxytocin, dopamine and
endorphins. When all these things reach a peak, the body releases all the
tension that’s built up in waves through the genitals. This causes contractions
within the vagina and usually results in ejaculation in the penis. The anal
sphincter, pubococcygeus (pc) muscle, perineum and other muscles join in these
contractions. Orgasms come in different sizes. They can be intense, light, last
for ages, last a moment, can happen only once, happen repeatedly with multiple orgasms,
and can be elusive and not happen at all.
