For me, I like a controlled environment.
I have done 141 HGs, though not too many. Bar pick ups in Wanchai, where I have scoped the place out, and is a short walk (I usually stay within a couple of minutes walk). And the chances of me seeing any girls who know me personally are very very slim, as they would be unlikely to be in the Wanchai bars I frequent. And if I saw a guy I know which is far more likely, as some of my trips are to attend trade fairs in HK, they are likely to be there doing the same thing. Fortunately my trade is very male dominated!
Or go over the water to Macau, and to be fair anyone I may or my not see in a sauna is there for the same
If I punt on my home turf UK, I only book with one agency outside my home town, who have apartments in residential blocks with underground parking with direct access lifts to the apartments.
But never on a day out on my home turf.
The closest I could be considered to taking a risk is on a couple of trips to HK when I did have time on my hands and spent a day out with a WG whose company I enjoyed. But still an 11 hour flight from home. Slim slim risk of being caught by anyone let alone anyone who would know my SO.
I know it may seem over cautious, but way in the past, I had almost been caught by my SO while attending an exhibition in the UK, on the day I was travelling, she told me she had arranged for her parents to look after the kids, so she could come and spend a couple of nights away with me!
I had already been getting a past lady friend of mine lined up, who was attending the same exhibition.
Not the adrenaline rush I'm after!
