This is a first printing of Dormitory Doll by Norm Kent, published by Playtime Books in 1963.  It has Robert Bonfils GGA cover art.

This is a "sleaze" paperback, a style of book that focused on novels centering around people engaging in abnormal sexual relationships.  The actual content of the books tended to be suggestive but not explicit or obscene, with a tendency toward melodrama.  Many of these formed the first exposure of things like lesbianism & homosexuality, open marriages, swapping, domination/submission, fetishism and nymphomania/sex addiction to the general public.  Some of the cover artists are justifiably famous.

From the publisher:

Sex goes on the program when call girl Janet is smuggled into college.
