this is from my experience folks! Nothing is more reliable than trying and testing by ourselves. A quickie has been always a quickie and long, erotic foreplay leads to longer intimate sessions.
I would invest so many minutes if not hours, exploring her body from dirty whispers into her ears, tiny love bites along the neck, sucking every bit of sweet nectar out of her delicious mouth, pampering erected & harden, milky nipples, super soft and inviting belly button are a few stops just before embarking on to worship the sweetest destination.
An unexpected moaning of the godess that you have come onboard to share all that was personal to her thus far, would instantaneously give you a hard on. What would be the impact, if your tongue could hang around and give her an orgasm, that she was dying to have for some time. So that would make you feel far more confident and let you play longer and harder!
