We actually have a partnership with a company that sells condoms and lube; one of the things they offer is a sampler pack of different lube options! That might be worth looking at if you want an idea of what different brands feel like. Here
is the page on our site where you can order the lube samples, and there's a link at the bottom of the page to their main website if you'd like to look at full-sized options too.
I get that it can be tough to order packages when you're living with parents who open things; could you maybe ask if they could start being more careful about that in general? It's a very reasonable request to make, and there are a lot of reasons people could want privacy around their purchases that aren't related to lube or other sexual items. In general, stores that sell sexual items online are very good about sending things in nondescript packaging and the official business name on the return label won't be a tipoff either. I know it's not foolproof, but I think ordering online will be the best way to get lube if going in a store to buy it feels like too much right now.
