About condoms?

Okay so i wanna try putting a condom on with my mouth for my boyfriend. Do you know which makes don't have lube on them, cos i don't want to ruin the moment and gag from the bad taste. I know ones Durex do, and i'm pretty sure Mates ones do too? Apart from them i don't know anymore makes apart from Boots own ones. I live in the UK if that helps and don't wanna order them online cos i live with my nosey younger sister lol.
