I am a 26 yr old female with 2 children. i don't get anything out of sex. why? what's wrong with me? shouldn't i love it and want to have it?

Many factors: You don't say how old your children are, or whether you have an ongoing, loving relationship. Women with very young children may simply be too exhausted to enjoy sex -- even though they used to. The qualities of relationships may change also, leading to changes in sexual interest. Depression can affect libido too. Seeing your family physician may be a good start at figuring all this out.
