It's not just a movie cliche, the old advice was people with heart problems should possibly refrain from sexual activity because the activity might be too much. I'm sure everyone has heard "ask your doctor if you're healthy enough to have sex" with the viagra type ads.

But the new thinking is that sex is actually more beneficial than potentially harmful for those with heart conditions. Not necessarily the sex drugs themselves, although boner meds were originally heart meds.

I can dig up a source if you want, but I won't be doing any googling you couldn't do. As it is my claim, I guess by tradition I will be your google bitch if you want me to.
