Sharing personal information brings people closer together. Verified by Psychology Today. All About Sex. Many women are happy to have lovers ejaculate in their mouths and swallow the semen. Others can't stand the idea. If women object to accepting semen orally, men should respect their wishes.
Semen contains numerous substances that influence its smell, and your individual diet, hygiene, and sex life all play a part. Certain foods can give it a sweet scent and taste! But eating or drinking acidic substances can make your semen smell foul. Some infections and conditions can influence its odor, too.
I mean pheromones. A pheromone is a fairly broad class of chemicals that signal information from one member of a species to another to trigger a response. Honey bees use pheromones to signal everything from the location of food sources to plans of attack 2 , and mammals like dogs and cats frequently give off pheromones that signal mating readiness 3 as anyone with a female cat in heat can attest to via howling tomcats outside their door. Scientists have been searching for human pheromones for decades, and what role they might play in human mating behavior. Along the way they have discovered pheromones that increase human reactions to fear 4 , aversive pheromones that cause male avoidance 5 , and pheromones that synchronize the menstrual cycles of women that live together.
