How is preseed as a general lubricant? My boyfriend is picky about lubes (haven't found one he likes yet) and unfortunately I usually need one. And since we're trying to conceive I know that the lubes we use are just going to make things more difficult anyway. I've read a ton of reviews about how its helped people get pregnant but can't find any about how it is just as a general lubricant. Does it get sticky and gross fast or does it last for awhile?
