My heart used to POOOUND in my chest as I approached a provider's incall, even ladies that I'd seen before. The thrill of it all, the anticipation, the wanting everything to go right, the agony of walking through lobbies, all made it worth it once I was there. Even knocking on her door and not wanting to disappoint her was tough. She would hug me and feel my heart busting through my chest, and be like, 'dude, why is your heart beating so hard/fast?' And I'd go through my myriad of excuses. A little nervous, yes (or a lot nervous). Or that lobby walkthrough was pretty tough if I was underdressed for it (not a good idea to go through a high end lobby looking like a low-budget rapper) or if it was very empty (I don't like being the only body walking through). Sometimes there's a flight of stairs, particularly if I missed the elevator (don't like looking lost in a lobby, so I'll take the stairs if I don't initially see the elevator).
As strange as it may sound, being a little nervous feels/felt better than not being nervous at all (I'd kinda GET nervous just because of this).
Then to get to her room, and see her, and she's all beautiful and cheery and inviting and looking like her pictures...
TOTALLY FUCKING WORTH IT!!!
