I hear exercising builds up testosterones and allows one to perform longer when it comes to sexual activity. Another possibility is that the men you met doesn't exercise or have a low sex drive. I don't notice a large difference, and its been many years since I last exercised (7 yrs since I left the military), so I can't make a good comparison between then and now.

To be honest, you should talk to someone before giving a key randomly and explaining it later. At least be upfront on what it's for, and if they accept the responsibility, then they could take the key. It'll be awkward to explain if your sister finds the key and asks what its for, or throws it away thinking its not anyone's.
