Is it harmful if you take a Viagra, and then don't have sex? Like, what if you took one by accident?I don't think people take Viagra "by accident" very often - although the tablets do bear some resemblance to the over-the-counter analgesic Aleve (ironic if you took something for your stiff back and something else got stiff instead).
If "by accident" you mean you misinterpreted your date's signals and she decides to go home early, well, that's a more likely scenario. Using Viagra takes some planning, and things don't always go according to plan.
So, if you take Viagra and don't have an appropriate "outlet", will anything bad happen? No, your penis won't explode, no matter what the drug pamphlet warns about possible "permanent damage to the penis". Unless you have an erection for four hours or more - then you should get to the doctor asap. Otherwise, the drug will eventually work its way out of your system and everything should return to normal.
If you become aroused while under the influence of Viagra and don't have an orgasm, you may experience pelvic congestion, aka "blue balls". This is usually a dull pain in the pelvis and testicles, caused by the pressure of accumulated blood. While this may be uncomfortable, it's not harmful, and if you don't do anything about it, eventually it should subside as the effects of the Viagra wear off (if not, see above). If you're not going to be having sex, the easiest way to relieve it is to masturbate. Repeat as necessary.
