Teela wants to bang He-Man.
Adam, who is also He-Man, wants Teela to want to bang Adam, and only Adam, because she should bang him for who he is on the inside.
Teela thinks Adam is effeminate, seriously that's a lot of pink, and a child, and the son of a set of Royals who can command her execution at a whim if their relationship goes badly, or she can't produce children fast enough, but mostly that he's 15.
If Adam/He-Man really is 15, then he certainly shouldn't be so caught up in what body he uses to make sweaty mclovin to a built stacked super cool goddess, because 15 year old boys are toxic one dimensional, superficial mouth breathers, but it seems like he does. He's more worried about his pent teen angst than his knob. Unrealistic writing.

I remember in the 1988ish Shazam comic book miniseries Billy, inside Captain Marvel's body thinking to himself "I wonder if the wisdom of Solomon can generate a line to impress this lady??" because he, a 10 year old boy, didn't know what to do when a fully grown woman, was flirting with him.
