What's in a number?

I recently found out someone I know, and care about has slept with more than 150 people.
I was significantly shocked, and a little discussed to hear this number.
I was more upset at the fact that this person seemed to hate themselves for this.

It got me wondering about all the self distructive and dangerous things we do in our life time.
Smoke
Drink
Date people who are bad for us
Drive dangerously

and obviously a very dangerous thing to do, have sex with SO many people.

I asked how this had come about.
I was told that up until the age of 23 this person had only slept with TWO people.
So how to get to 150 in less than 20 years.

Relationships and sex can be such a manipulating situation.
Sex in my eyes is a wonderful and amazing thing that everyone should enjoy when the time is right for them.

Seeing someone hate themselves for sleeping with so many people made me realise how thankful I am that my number of partners is small.
Sex for me, must be accompanded by trust.

That much sex to me would mean a very low self esteem, lack of self control and ammount to no self worth at all.
Oh and a love of sex.

But really who doesn't love sex?

I was also slightly upset at myself for being so discustsed in someone elses decisons.
But I think it was more so guided in the fact of the pure self hatred that was coming from this person.

So really, what do you think.

Do numbers like that matter?
