9. Fear of what to say

Some couples enjoy using crude language and even the most refined lady when sexually aroused may ask her man to make love to her using unutterable words. This is a great turn-on for most men especially when it gives him a harder erection and enables him to penetrate his partner more deeply and enjoyably. However, the need for talk can be a sign of inhibition, and if not rational, can offend  the other partner who feels the talker is not as immersed in the pleasure as they should be.

10. Fear of the unknown

Sex, like all the best things in life, is an adventure! Jump in with enthusiasm!
