Douche on Plane

Hey guys! So I'm flying on Friday for the first time in a very long time (10-12 years) and I'm going with my Boyfriend. I was wondering if it's possible to bring a douche with me on the plane without my luggage getting checked, otherwise i'd feel embarrassed if they took it out my case to check what's inside it. I'm flying from England to Spain if that helps. Thanks guys!
