Yes. You may lose the ability to achieve or maintain an erection – resulting in anxiety about attaining a hard-on in the future. But that’s if you break the legal blood alcohol limit of 0.08 per cent. A little red wine can improve circulation and facilitate an erection, but I still wouldn’t recommend the use of alcohol prior to, or during, sex. That’s largely because alcohol is a depressant, which can make the body’s natural and physical response to sensations in sensitive areas less intense. Not to mention, long term over-consumption of alcohol negatively affects the whole body, including sexual functioning.
