Not sure if you're specifically looking for romance anime but these are all from that genre: Kimi ni todoke (guy is shy around mc) Horimiya (leading male character seems right up your alley) Ookami san and her seven companions (guy is so shy, he can't even stand to be looked at). All of these anime series have a large cast of cute (or attractive) anime boys/men, though the art styles (as well as the genres) vary, so you may not find some of the series as appealing as others. I figured I'd give a good amount of variety though.
