Well so far ive only tried the calais! It seems to be top notch!! Ive never had a problem with ED and always thought my tackle was top notch and highly responsive! But after taking the cailis i cant even take a piss without it going full bar within 10-20 seconds :/ the moment im thinkin about the female figure im as ready to roll as a teenage boy!! I made the mistake of wearing loose trousers today and pretty much spent the hole day walkin around the shoppin centre tucking the tackle in my pocket cause shit was getting awkward!!!! GC cailis is excellent! As always!
