Male's Super Food: Lean Red Meat
If you're a steak-and-potatoes guy,
you're in luck. Red meat can be good for you, says Leslie Bonci, MPH, RD, a
dietitian for the Pittsburgh Steelers. Lean cuts of beef and pork are packed
with protein and have only a little more fat than chicken breast. Red meat is
also a good source of leucine, an amino acid that helps build muscle.
Sex Mistake No.1: 'I Know How to Please a Woman'
Men often assume that the way they've learned to please one woman works for all women. Not so.
"With every sexual partner you have, you do gain a growing body of knowledge of female bodies and female pleasure," Taormino tells WebMD. "But women's sexuality is complicated, and it's really individual."
Every woman's body responds in different ways to sensation, and every woman's anatomy is a little different. What feels amazing to one may do nothing -- or even cause discomfort -- for another.
"That is the detective work you need to do each and every time," Britton says. "We really each have a sexual fingerprint."
When it comes to intercourse, one key variable is your thrusting technique: Does she like it fast or slow? Deep or shallow? Or does she like to mix it up -- slow and shallow at first, and then fast and deep?
Also, no one sex position is every woman's favorite. She may prefer a certain sex position for several reasons. Different positions allow various angles of penetration, depending not only on her anatomy, but also the size and shape of your penis. Differences between partners' body shape and height may make some positions better than others. And for some women, it's important to have face-to-face intimacyduring intercourse.
"I talk to tons of women who say, ‘I know missionary gets a bad rap, but I really like it.' Others say, ‘It's got to be from behind,'" Taormino says. "People are really across the board when it comes to positions."
Organism and Sex
An organism's sex is defined by the gametes it produces: males produce male gametes (spermatozoa, or sperm) while females produce female gametes (ova, or egg cells); individual organisms which produce both male and female gametes are termed hermaphroditic. Frequently, physical differences are associated with the different sexes of an organism; these sexual dimorphisms can reflect the different reproductive pressures the sexes experience.
Sex and Sex Process
In biology, sexual reproduction is a process of combining and mixing genetic traits, often resulting in the specialization of organismsinto a male or female variety, each known as a sex. Sexual reproduction involves combining specialized cells (gametes) to form offspring that inherit traits from both parents. Gametes can be identical in form and function (known as isogametes), but in many cases an asymmetry has evolved such that two sex-specific types of gametes (heterogametes) exist: male gametes are small, motile, and optimized to transport their genetic information over a distance, while female gametes are large, non-motile and contain the nutrients necessary for the early development of the young organism.
