well, my bf likes using the durex 2 in 1, but ive heard that the liquid silk is the best all rounder lube, very slippery, long lasting and tasteless and odourless :)
And welcome to the forum! hope to see you around ^_^
id try it now but the other half has just finally got to sleep (its next to her!) despite coughing a lot and i'd get into a lot of trouble if i woke her for a taste test!!
Hullo and welcome! I'm a huge fan of liquid silk so it's my first choice. There are others though like sliquid. Just go by the reviews of the actual texture etc because otherwise people all have different favourite lubes and it'll be impossible to choose! Decide what texture, smell etc you'd like and find a lube to fit those requirements.
Nope, anything you use externally kinda has to be used internally as well!! Basically lubes were first designed to aid a woman's natural lubrication. Now they can do a lot more than that!
For a handjob you'll want to look in the water based lubes section (http://www.lovehoney.co.uk/store.cfm?cat=38) for lubes with reviews that say the lube lasts or doesn't dry out too quickly, alternatively you could go for a silicone based lube (http://www.lovehoney.co.uk/store.cfm?cat=39) as they generally last a lot longer, and feel more silky, two things that'd be great for a handjob lube.
