Other times the semi-on can occur include:
* When the individual is too drunk to support a full erection,
* When the individual is somewhat aroused but controlling the feelings and suppressing the erection,
* When the individual is interrupted during sexual activity (or thoughts) but was turned on enough that the erection did not immediately disappear.
