It's kinda funny, whole websites have been devoted to He-man being gay when actually nothing could be further from the truth. As Prince Adam he's quite the flirt with the ladies and as He-Man he has a very warm connection with Teela.
But it was in the follow up series "She-Ra, Princess of power" that we truly got to see what He-man's sexuality is.
In the She-Ra episode "The Eldritch Mist" Adora and her friend Castaspella are looking in an inter dimensional portal and see Prince Adam taking a nap at the royal fountain of Eternia's castle. Castastella then looks to him with an appreciative smile before using her magic to "accidentally" transport Prince Adam to Etheria, when the two meet, it's instant chemistry.

and I show what could have happened if the two of them had spend more time together.
