Hair Tie In Shower- UPDATE

Hi all!

I just wanted to say thank you for all the responses. I ended up leaving it in the shower to see if he'd get rid of it "before I noticed it" Well, that plan was foiled because he didn't take a shower that night or following morning.

There has never been anyone else to use our shower besides us in the 2 years we've lived at this house.

I went to take a shower the following morning and he was at the bathroom sink getting ready. I stood there longer than necessary outside the shower prior to starting the water which caused him to ask what I was doing. I then replied with "trying to figure out why there is a hair tie in here" He simply went "Hm" and walked out of the bathroom and continued to get ready for the day. I jokingly asked if he was tying his hair up (he has a short crew cut) He replied/joked back with "oh yeah, all this hair always gets in my way!" He then told me he had no idea where it came from. So, as of now I'm just not sure what to think. I would love to simply believe him but it's proving difficult. I love him so much, we have 2 boys and were going to start trying for our third this spring.

(I did wonder about the experimentation/cockring idea because I know he most likely would not admit to that but then where did the damn hair tie come from since it's not mine?!)
