I'd agree with porkchops. I'm no spring chicken myself and I had a good time with some 141 walkups. You can search my usercode to locate my reviews of Walk-up girls at Phoenix,Causeway Bay:

Keep in mind that I don't have the extensive HK punting experience of porkchops, and there may well be other, better places. Those reviews are based on a couple of one-week visits to HK. The resources on this Forum were very helpful. There is a thread linked in the Forum Guidelines section on how the 141walkups work:

Most of the girls in Phoenix with a "Blogger" speech bubble would be at least in their 30s, and have been around for a while. I found all of them very friendly and helpful, though sometimes English is a challenge. You might particularly enjoy meeting Joanna, on level 3.
http://forum.sex141.com/eforum/viewthread.php?tid=67372 She speaks excellent English, has great massage skills, and the first time I met her we had a nice chat about my needs (nothing particularly special about my needs: I find that rough, fast blowjobs or sex tends to kill my sensitivity - I prefer a slower approach). She did do rimming also. All part of the service when I did the sex+massage option which was $888...
Several of the others were great, but their English was not really up to discussing specifics.
I never actually made an appointment, though I did chat a little with Joanna on WeChat (if you put a phone number into your contacts you can find many of these girls on WeChat, though they won't always respond...), and we exchanged New Year greetings... My approach was to have a list in my notebook and pick someone who was free. Quietest time seemed to be mid-afternoon on weekdays. Lunchtime is busier.
Good Luck!
