My dics fail to offer relative info.
Context:
Biologic Plausibility
Compared with the dry external skin surface, the inner mucosa of the foreskin has less keratinization (deposition of fibrous protein), a higher density of target cells for HIV infection (Langerhans cells), and is more susceptible to HIV infection than other penile tissue in laboratory studies [2]. The foreskin may also have greater susceptibility to traumatic epithelial disruptions (tears) during intercourse, providing a portal of entry for pathogens, including HIV [3]. In addition, the microenvironment in the preputial sac between the unretracted foreskin and the glans penis may be conducive to viral survival [1]. Finally, the higher rates of sexually transmitted genital ulcerative disease, such as syphilis, observed in uncircumcised men may also increase susceptibility to HIV infection [4].
When a man's penis is not in use sexually, the foreskin covers the glans area on the underside of the penis. In such a position, the foreskin is said to be "unretracted," that is, is still covers the "head" of the penis.
I'd draw you a picture, but i don't think the moderators would allow that.

Got it. Thanks.
But I don't get the meaning of the word "underside" very well. Is the root area of penis called upperside (of penis)?
This is going to be more information than i really cared to give. Imagine a man standing with his penis semi-erect. The part he can see by looking down is the upper side, the part which he cannot see is the underside. The glans is the area of the penis on the underside immediately below the head of the penis. I'm not going to link and image here, but i suggest you put "penis+physiology" in a search window, and then click on images.

Still confused because my dictionary tells me that "glans" is "the head of the penis." See the pic in the link below:

That's not what i recall from university pysiology. But far be it from me to contradict your dictionary. I've already posted far more than i ever would have wanted on this topic. This goes far beyond explaining unretracted in context.

Let's call it a day, then.
Thanks.
the foreskin covers both top and bottom (and sides) of the glans, not just the bottom, or most of it. Unless the man is circumcised, in which case the foreskin is not there at all.
Stumble It!
