never sucked at a gloryhole, but curious

[nakedsteve]

I've been sucked countless times over the last 38 yrs, in ABS glory holes from California, to NY and the last 25 years in Tampa,FL. Lately I'm very curious, but soooo nervous. Worried about STDs as I'm married, and not sure even how much of a cock I could get in my mouth. What if I started and didn't like it? Not sure I'd want to swallow a load my first time either. Maybe suck for a while then finish with my hand? Would to hear any advice... there's a nice clean ABS in St Pete, not to far from me called Jack and Jills, with locking doors and nice glory holes.
