I was totally confounded when Lance Armstrong and Sheryl Crow broke up. I was trying to figure out what went wrong and when I heard that Sheryl Crow still loved Lance after they ended their relationship, I was confused even more. Then, Sheryl Crow adopted Wyatt Steven Crow and I suspected that we would never find out what went wrong in such a beautiful relationship.

Now we have answer. The main reason for the breakup was Sheryl's desire to become a mom, as she was already 44 around their engagement. At that age, it is nearly impossible for a woman to get pregnant naturally and have a healthy baby. Yes, some women do become moms but in almost all cases they resort to IVF that may use their frozen eggs, of if that was not done, they use donor eggs.

"She wanted marriage, she wanted children; and not that I didn't want that, but I didn't want that at that time because I had just gotten out of a marriage, I'd just had kids [Luke, Grace and Bella]. Yet we're up against her biological clock -- that pressure is what cracked it." Armstrong says in a book.

They tried counseling but it seems that he was not ready to father another child at the time and Sheryl wanted to get pregnant right away since at that age every day matters. In the end, the couple could not come to a compromise and decided to cancel the engagement.

The message here is that parenthood and its timing can be a big bone of contention in a couple and it is better to deal with it very early on in the relationship rather than realize that it is a problem after the engagement.

Remember how I advised a mother who wanted to make sure that his son lost his virginity at home rather than in the back seat of a car. Well, that is exactly how Sienna Miller lost hers.

She shares her secret, "I had my first serious boyfriend when I was 16, and my mother made sure I brought him home. She didn't want me doing it outside and would say, 'I'd rather you did it in my house if you're going to do it at all."

The lesson to all parents is that if you pretend not to know or continue to wrongly believe that your children are not having sex, then you are in denial, or even worse, like Sarah Palin, end up being parents of a teenage mom. In other words, be involved with your kids, and make sure that you facilitate safe sex since they are going to do it anyway.

I know a lot of young guys likes mature women but losing your virginity to an older woman -- only Harry Potter, I mean Daniel Radcliffe, can do that.

He disclosed that although the age difference (he was 16 and it was probably illegal for the woman to do it) "wasn't ridiculous," it likely "would freak some people out."

A lot of women ask me how they can seduce their men or how to make sure that she is the center of attention of a man.

The answer probably is best given by Jessica Alba who told Entertainment Weekly magazine, "Guys are visually stimulated. They're easy to manipulate. All you have to do is dress up in a sexy outfit. Girls just have this power over guys. Guys are sort of stupid that way."

A lot of men have this wrong idea that because they are male it is their duty to satisfy a girl in bed. If they do not perform in bed and the woman does not orgasm, somehow they are less of a man.

Indeed, for a good relationship, it is important that both partners are able to please each other, but they can sure learn something from rapper Lil Wayne (who lost his virginity at age 11).

In answer to a question if he was good in bed, he told the Playboy magazine, "I would say what makes me good in bed is that I am not aiming to be good."

Many guys are obsessed with Megan Fox and their girl friends wonder what is it that makes them men so much in love with this woman. Well, she lets her secret out and discloses in an interview that, "I have the libido of a teenage boy. I'd rather have sex all the time than leave the house."

This positive attitude towards physical intimacy is what keeps men hooked on to their women. In other words, if you think that your libido is lower than that of your partner, you can either work on it with the help of a therapist or if you are not willing to do it, then just end the relationship so that you do not have problems in the relationship later on.

Wilmer Valderrama girlfriends

Wilmer Valderrama can best be described as a Playboy. He claims to have taken Mandy Moore's virginity, describing the honor as "really good."

So what more juicy details have come from him?

According to this Latin lover, Lindsay Lohan was one of the best girls he's ever been intimate with.

Ashlee Simpson was loud in bed and rating Jennifer Love Hewitt an "eight" out of 10 when it came to making love.
