Penis Health - Stimulants

Cigarettes - You may think that smoking a cigarette makes you look more manly, but the reverse is actually true, as smoking can affect the arteries that allow blood to flow to the penis. These arteries are especially narrow, so they can be the first to be impacted by smoking, leading to problems with achieving or maintaining an erection.

Alcohol - Drinking regularly can inhibit both erection and orgasm. Alcohol does this by affecting the production of nitrite oxide molecules, which then makes it difficult for enough blood to flow in the penis. If drinking continues over time and alcoholism develops, there is a possibility for more extensive damage to occur. The peripheral nervous system can be injured permanently, thus affecting the ability to have or maintain an erection

Drugs - Some drugs, such as ecstasy and cocaine, can lower your inhibitions and make you more likely to indulge in unprotected, unsafe sex. This obviously increases the risk of being infected with an STI including HIV via sexual contact. Some drugs can also interact dangerously with other drugs used to increase sexual performance. For example, taking poppers with Viagra can lead to a rapid lowering of blood pressure and possible stroke, heart attack or death.
