There are many perks of masturbation. It
helps relieve stress, helps you understand what your body likes, and
helps you find pleasure when you don’t have a man. But how exactly does
your body react to masturbation?
Here are three main things that happen when you masturbate.
1. You get aroused
Arousal in the case of masturbation
isn’t substantively different from arousal in sex with partners; your
body reacts in the same way. The most obvious reaction to arousal is
the vag ina lubricating and cli toris hardening with blood. Arousal
during masturbation will cause everything from muscle tension to a
quicker pulse and the rearrangement of the uterus inside the body,
retracting slightly in order to help penetration (useful if you’re using
a toy). And the brain’s reward circuit is being bombarded with
pleasurable messages, with positive neurochemicals swilling around to
prompt some serious mental highs.
2. The imaginative center of your brain comes on
Arousal and orgasm light up the brain
like a firework: the hippocampus, amygdala, cerebellum and
hypothalamus combine to get you to your peak. But that’s not all. We’re
gradually beginning to understand that (in the female brain at least)
the mental patterns of arousal and stimulation visible in the brain
actually differ between partner se x and solo masturbation. And a lot of
it seems to be involved with fantasy and our brain’s capacity for
imagination.
Back in 2011, New Scientist reported
on two competing studies documenting the female brain at the moment of
orgasm, which seemed seemed to indicate two very different things. But
it turned out that the studies had one crucial difference: in one, the
subjects were being aroused by their partners, while in the other they
were solely responsible for their good vibes, as it were.
And
the brain seemed to react differently to the solo adventure. In
masturbation, the female brain’s prefrontal cortex, an area of the brain
heavily associated with creative thinking (you can actually zap it with
electricity to spark some imagination), turns up the volume. In the
case of partner sex, it seemed that certain elements of it actually
turned off, specifically the part that seems responsible for
self-control.
Interestingly,
female masturbation also seems to have the benefit of lowering the
possibility of vag inal and urinary tract infections through clearing
out accumulated bacteria in the vag ina through a process called
“tenting,” a function during arousal wherein the uterus is drawn upwards
and the cervix withdraws a bit. The process of tenting stretches and
pulls the mucous within the cervix, allowing for a rise in acidity in
the cervical fluid. This increases ‘friendly’ bacteria and allows more
fluid to move from the cervix into the vag ina. When ‘old’ fluid moves
from the tented cervix, it not only lubricates the vag ina, but also
flushes out unfriendly organisms that can cause infections.
