I don't think craving is something that you experience directly, it seems to be more a tendency or an attitude that gives rise to suffering.
Actually, the suttas make a much broader claim than the one I'm prepared to defend, namely, that craving is experienced everywhere (extended over all modalities of experience), not just in the body. The craving experienced in the body that I like to talk about would seem to be a subcategory of the general phenomenon.
http://www.accesstoinsight.org/tipitaka/dn/dn.22.0.than.html:
"And what is the noble truth of the origination of stress? The craving that makes for further becoming — accompanied by passion & delight, relishing now here & now there — i.e., craving for sensuality, craving for becoming, craving for non-becoming.
"And where does this craving, when arising, arise? And where, when dwelling, does it dwell? Whatever seems endearing and agreeable in terms of the world: that is where this craving, when arising, arises. That is where, when dwelling, it dwells.
"And what seems endearing and agreeable in terms of the world? The eye seems endearing and agreeable in terms of the world. That is where this craving, when arising, arises. That is where, when dwelling, it dwells.
"The ear... The nose... The tongue... The body... The intellect...
"Forms... Sounds... Smells... Tastes... Tactile sensations... Ideas...
(etc.)
Fivebells, about the suttas and dukkha:
http://www.accesstoinsight.org/tipitaka/dn/dn.22.0.than.html:
"Now what is the noble truth of stress? Birth is stressful, aging is stressful, death is stressful; sorrow, lamentation, pain, distress, & despair are stressful; association with the unbeloved is stressful; separation from the loved is stressful; not getting what one wants is stressful. In short, the five clinging-aggregates are stressful.
(...)
"And what are the five clinging-aggregates that, in short, are stress? Form as a clinging-aggregate, feeling as a clinging-aggregate, perception as a clinging-aggregate, fabrications as a clinging-aggregate, consciousness as a clinging-aggregate: These are called the five clinging-aggregates that, in short, are stress.
http://www.accesstoinsight.org/tipitaka/sn/sn22/sn22.048.than.html:
The Blessed One said, "Now what, monks, are the five aggregates?
"Whatever form is past, future, or present; internal or external; blatant or subtle; common or sublime; far or near: That is called the form aggregate. (Same for the other aggregates.)
These are called the five aggregates.
"And what are the five clinging-aggregates?
"Whatever form — past, future, or present; internal or external; blatant or subtle; common or sublime; far or near — is clingable, offers sustenance, and is accompanied with mental fermentation: That is called the form clinging-aggregate. (Same for the other aggregates.)
"These are called the five clinging-aggregates."
If you have a more specific question that you'd like some sutta references for, I can try to find them for you if I know the appropriate suttas.
