Welcome to Basenotes, wodorost!
There isn't an automated recommendation system based on your buying history -- not at Basenotes, anyway. But I recommend that you enter the fragrances you own into your own "wardrobe" page here at the site. (To do this, use the Directory to find the page for each fragrance, and from each of those pages, change the setting in the drop-down menu at the left to "I own this".) Once you have an online record of what you own and like, more experienced folks here the site can have a look and make recommendations, which is probably more useful than an automated system.
