Not tested them in LA — the city is so big, and not that easily navigable in my experience there, plus it’s mostly unlike any other US city in terms over avoiding scams so I’d do a lot of research if I went back (the American ISG would be a place to start).
But one thing I think is worth it if you start doing the lap dance bars anywhere in the US — whether the expensive ones (where a reasonably-priced shag is unlikely) to the apocalyptic suburbs which I prefer but are only for those who know how to manage themselves there (excellent shagging and lap dances and BJs!) but anyway — to get the best from a decent lap dance you need a pair of ‘liquid lap dance pants.’ The girls know what they are, and if your lap dance turns into a negotiated shag or bj there’s no embarrassment. Basically it’s a latex pouch-style men’s underwear. So when she’s grinding in your lap it keeps you comfortable, slides over the hard-on like a glove, and you get the full benefit. Some guys add some lube down there (which I don’t, but you could also come like that and no mess in the pants) in which case it’s ok to say to the girl you want to go and change before a bj (so as not to surprise her with a sticky cock!)
America. Crazy place!
