Used To Be

I have always been the horny, frisky one in the relationship. always the one chasing for sex and passion and wanting to try new things, lately though I have noticed and maybe its because I haven't been to happy with the relationship but the last few weeks or so I have noticed I haven't been in the mood anywhere near as much, maybe its because I haven't had anyone to interest me (don't get me wrong if my wife was standing in front of me in some sexy lingerie I would be hard as a rock in seconds, I have always been that way towards her, she is such a turn on even after so many years) but knowing she isn't interested to often I don't think the arrousal is there or maybe It's just my body/mind telling me to lay of the sex and find other ways to have enjoyment. if this is the case it might be a hard ask but who knows it might just be the one thing missing in my life. time wil tell.
