I don't think that would be a Greek goddess if she can only take 3 inches. LOL
I'm not sure when I'll be back to SA however I love it most of the time and size usually isn't an obstacle as long as properly prepped and lubed. And if done right, expect a wet and wild ride.
Considering your signature girls should know they are in for a big surprise. Sounds like she didn't screen you enough for a greek date. Nothing against you of course, but girls should know their limitations and not book appointments that they might have a problem "accommodating".
Tammie has it right. With the proper prep, right mindset, and sufficient lube most guys can be "accommodated" very pleasurably.
