Is it unsexy to tell to much?

So I have a coloscopy soon and for this I have to drink a laxative. So I'm in a "fresh" relationship (a few months) and now I am not sure if it is too much to tell him that I have to take that laxative. Is that too much information or make it me unsexy for him? Or what is you're opinion about it
