How does smoking affect my sex life?
Some people think that a cigarette after sex actually enhances the pleasure. The reality is that it does. Sexual orgasm release is wired through your pleasure and reward centre to release dopamine to feel good. It's the most intense natural response of the human reward centre. Nicotine boosts that, and so a cigarette after sex really does feel better than a cigarette by itself. However, there are prices that you pay for cigarette smoking. Blood vessels are constricted by cigarette smoking, and over time the lining of the arteries are hardened so that they can no longer dilate and constrict, and that's the whole mechanism of a male erection and female erection. I would encourage people who are starting to have erection problems, to first go talk to their doctor about quitting smoking. That's much safer and cheaper in the long run than continuing to smoke and just taking medications or having surgery, or other ways to try and correct impotence.
