Want to know a creepy fact about your man’s penis? It probably used to have spikes. Obviously this isn’t something that happens these days. It was common long before even Neanderthals were roaming the earth. Spiked penises are something that have been speculated about by many scientists, out there for quite a while now. Cats are one example of creatures with spiked penises, and scientists believe that humans developed penile spikes as well because spikes apparently quicken the pace of an erection.

Want to know one of the weirdest facts your vagina? It can expand. Yes, your vagina is built in an ingenious way that allows it to expand itself when needed. Your vagina is about 3 inches in length normally. However, during the sexual intercourse, your uterus will be pulled up to make more space for your guy to enter you. Usually, this means that the length of your vagina will expand itself to about 5 inches, but if your man is particularly gifted, this length can be even larger.
