I am 25 old stile I am't do sex?

You are 25 and have not had sex. Is this correct?

Not sure what country you are in, but here is some general information on age/virginity statistics.

How many people over 25 are still virgins? - Barking up the wrong tree (http://www.bakadesuyo.com/how-many-people-over-25-are-still-virgins)

For more specific information on where you are, if you aren't in North America, try googling the above, but put your country in.

As to whether it 'matters' is entirely a personal preference.

Sex doesn't make the person... sex is sooooo much better when it comes naturally,the right man/woman and the right time and place. I wouldn't worry about being a virgin until I was too old to worry about it.

Most have sex too early and without proper regard. So age and time makes little difference

Good for you. When it's time you'll know!
