Yoli chiming in (as you just KNEW she would:D)
Wait a sec...YAWWWWWWN...MORE KAWFEE!
OK, all better.
Speaking empirically I can state that MY perineum IS an erogenous zone (whereas my brain is often an erroneous zone,) and I have no balls. Being a genetic girlpuppy pretty much means I wouldn't anyway.
That said, I can report that the two castrated individuals, Barry T. Eunuch and "my" Thai ladyboy friend, with whom I am THAT intimate both enjoy touching, caressing, and skillful tongue "tracing" on their perineii I will ask Houston Eunuch #1 if he does as well but have no intention of conducting any "hands on" research between his saggy baggie and his exhaust exit.
When I'm attempting to elicit an orgasm from either of them via oral or manual attentions to their peepees I usually massage the interior portion of their peepees via pressure applied to their perineums. As is the case with my one-and-only intact sex partner, BigGuy, the same technique is most effective, especially when attempting to trigger the third, even fourth (sometimes) orgasm in a row. He can do that, y'know:)
Sooooo...If you want a bigger "O", pay attention to the "P" (and the PeePee!).
I'm sooooo moist "down there" and salivating like Pavlov's Pups as well. Of course, the upper moisture might be related to the huge Cheese Danish I'm eyeing at the moment in addition to the thought of a tasty eunuch peepee in my warm little oral cavity. Where's that *&^$%! Barry when I need him? (Well, he's in Lubbock. After all, he lives there.)
If you'll 'scuse me I need to go molest Ash(leigh)...NOW! She might not have a

but she knows what buttons to push and nibble. Thank God she's already awake in prep for a trip.
Byeeeeeee...
