The sexual feelings a person goes through while waiting for what they anticipate to be a life altering sexual experience.
I have a friend who is anticipating their first sexual encounter with a person of the same sex. The two have agreed to meet and both understand that it will be an explorative encounter. The problem is that the date will not happen for nearly a week.
Now my friend is experiencing an extreme case of ANSEXIPATION; Anticipating sex with another woman and being so fucking turned on that she can hardly stand it! Ansexipation!
