If you're choosing to wait to have a given kind of sex or all sex, the reason you are waiting is MOSTLY because

I want to be married first.

I want to be with a partner where I know there is love, respect and trust first.

I want to feel better about myself, my body or sex in general first.

I want to have a better handle on birth control and/or safer sex first.

It just hasn't felt right yet.

I want to be a certain age first, or out on my own.

I'm not sure why, or for some other reason.

I'm not waiting or didn't choose/am not purposefully choosing to wait.
