Virgin na Kankei

Both have male protagonists that were quite unpopular with girls, but somehow become chick magnets later on.
Both are borderline hentai. Similar happenings of harem in both mangas. Virgin Na Kankei is more focused on ecchi stuff while Love Junkies is more on the psyche of the people involved.
Love Junkies has a much deeper storyline than Virgin Na Kankei and is heavier at times.
Both feature circumstances in workplace as well as out of it.
