The beautiful thing about sex is that it can be completely and utterly spontaneous. You never know when feelings are going to strike, or when the timing is going to be perfect for you and your partner to slip away and have some fun.

But when you develop erectile dysfunction, spontaneous sex can prove difficulty. Sure, you can engage in plenty of foreplay, but eventually you’ll need to get down to brass tacks. If you rely on ED medication to achieve an erection, you may find yourself waiting for the drug to kick in.

And if you decided to chow down before popping that little pill, you might find yourself waiting even longer.

For medication to work, it must be digested by the body and dispersed throughout the bloodstream. For ED medication, once the pill has been digested and processed, your arteries will open up and blood flow will improve, which will make it easier for your body to achieve an erection.

But a full stomach slows this whole process down. If you take ED medication after a meal, your medication will essentially have to get in line. The food in your stomach will be digested and process first, and your little ED pill will have to wait for it’ turn.

Viagra typically takes 30 minutes to an hour to take effect, but if taken on a full stomach, you might yourself waiting for up to 2 hours for your erection to spring to life.

So if you’re looking to delay the effects of your erectile medication, then down the pill with a heavy meal. Otherwise, avoid food when ingesting ED medication or you could find yourself playing the waiting game.
