Believe it or not, lots of people have had orgasms inside fMRI scanners. For science.
First, genital stimulation sends a signal to your limbic system that it’s go time.
Speaking of rough sex, some brain areas respond to both orgasm and pain.
And about all those weird facial expressions and curling toes…
That’s because activity in your cerebellum is steadily increasing, which is responsible for increased muscle tension related to sexual stimulation.
BOOM – ORGASM.
During orgasm, you release oxytocin.
This is a hormone and neurotransmitter produced by the hypothalamus. In many women, oxytocin can trigger strong uterine contractions that pulse along with their orgasms, says Komisaruk.
You may have heard it referred to as the “bonding hormone” or the “cuddle hormone,” but Komisaruk stresses that the research doesn't show that oxytocin produces emotional feelings. Instead, research only shows that oxytocin is an effect of orgasms.
