Thanks for the query to ATD for an opinion,
The presence of itching and sagging of penile skin indicates a possible fungal infection. This can be confirmed with a swab culture test and if confirmed shall required oral and local antifungals course. This can be transferred sexually and also can be contributed by poor hygiene.
Nevertheless, it is important to get a swab culture done and get yourself examined by a dematologist to seek an early treatment.
I hope i have answered your query,
Wishing you good health,
