In a study that will certainly be forwarded to husbands everywhere, a team of Italian researchers have determined that an active sex life keeps men more heart-healthy and therefore, alive longer. Diabetic men seem to get even more beneficial effects from sex and regardless of blood sugar levels, getting schtupped regularly is great for the prostate. However, all health bets are off once a guy steps out on his lady (or man) …According to Dr. Emmanuele Jannini (owner of the sexiest name ever), in a study conducted at the University of Florence, “Increased sexual activity produces more testosterone, which leads to less depression and a better cardiovascular performance which means an improved metabolism.” More testosterone also helps the body burn off excess sugars and decreases the chance of heart disease and osteoporosis. However, all these health benefits can be negated by the stress of infidelity. Making sure you whisper the right name during sex … keeping track of which one likes her nipples tweaked and who likes them pinched … and who’s a multi-orgasmic squirter and who needs a good 20 minutes of foreplay—who can keep track of all that? Especially when you’re juggling multiple partners who all believe they’re your one and only! The result: decreased cardiovascular function. Not to mention the ever-present danger of getting beaned in the head with a frying pan. Unrelated, but kinda related: A British survey of users of a dating site for married folk found that hip-hop lovers were more likely to step out than any other kind of music fan. However I’d take any statistics culled from a liar’s website with a big grain of salt. Getting back to the Italians—the same conference where these findings were announced also revealed a study that showed men who used their cell phones often were more likely to have lazy swimmers (i.e., their sperm had decreased mobility). Andrea Lenzi, president of the Italian Society of Andrology and Sexual Medicine (SIAMS), said: “The waves appear to put the sperm to sleep.”Do you think we’ll ever be able to use BlackBerry as birth control?
