My first punt was with an escort in Amsterdam.
Had gone over for the weekend, wandered around the red light district at night and along with other tourists and the odd punter negotiating at the door, found it tacky.
Went back to my hotel a bit horny and thought "The hell with it. I'm in Amsterdam and it's famous for sex" so flicked through the phone book in my hotel and picked one of the many escort ads and rang it about 8pm.
Really nervous but asked for a girl and was told around 10pm.
After that, ran down the street to a cashpoint when a man on a stag night told me about his visit to a Kamer.
Back to the hotel, showered and changed and was absolutely bricking it - other than sitting on a rollercoaster, never been that nervous / scared or the unknown before.
Girl arrived about half an hour late after the phone rang and it was reception telling me my guest had arrived (lets say I waited until a shift change before I went downstairs as I was so embarrassed).
Nice time although really nervous throughout and it took an extra hour for me to complete.
As for pills, first time I tried one was when I was temporarily living at my parents house a few years ago. Bought some (Kamagra - they're green) off the internet and broke one in half.
Within a few minutes, started to feel warmer, got a blocked nose, became more flushed over time and an erection like a steel rod! Like being a teenager again.
Since then, if I use one, I know to reduce the dosage slightly and take a couple of hours earlier than required so the signs aren't quite as visible.
Even taking the pills though, if you're not horny, they will have a negligible effect - I have had a couple of occasions where I wasn't overly enjoying the session and lost my erection.
I do find the harder the erection, the longer it takes me to complete.
