Molluscum is very common in adults. It is also very common in children. Most cases are not even associated with sexual transmission, much less HIV. Untreated HIV patients may get huge numbers of mollusca, but ordinary mollusca, which are what you seem to have, are mostly associated with good health otherwise. If you don't treat mollusca, they go away. if you do get them frozen or dealt with some other way, they go away faster.
