Little lady does raise an interesting point about the taste of semen. It must be remembered that semen is composed of 96 percent water, plus:
• Sperm, which account for about 2 percent of ejaculate volume.
• Fructose, fruit sugar, which nourishes sperm.
• Vitamin C, which helps keep sperm healthy.
• Sodium bicarbonate, an alkaline compound that protect sperm from the slightly acid environment of the vagina.
• Various proteins and enzymes.
• A several minerals: magnesium, phosphorus, potassium--and zinc, which gives semen its odd, metallic taste.
Fruit juices are often recommended to sweeten semen, notably, apple and pineapple. Meanwhile, foods reported to foul the taste include: meats, dairy, deep fried foods, coffee, alcohol, and asparagus (which makes sense because of its well-known ability to alter the aroma of urine), plus one nonfood item, cigarettes.
Internet discussions have said that vegetarians taste best, that eating fruit and drinking fruit juices a few hours before sex improves the taste.
