Libido low, Male age 46

Hi there, I've suffered from zero sex drive for a good few years now, just wondering are there any other males out there that have this problem. As a youngster in my teens, 20's / 30's I was constantly horny, If I wasn't having sex I was masturbating. Now at 46 this has all disappeared, I get zero urges, and even if I engage in sexual intercourse there just isn't the passion inside myself anymore, I just cant be arsed. As for an erection, I'm ok, no problems there, its the same as its always been. Testosterone is fine I've had that checked. When I ejaculate the intensity is no where near as strong as it used to be years ago, is this normal?. I don't get turned on easily, for me it has to be a dangerous situation to be able to get me anywhere near wanting to ejaculate, IE. being outdoors with a partner engaging in oral sex etc, the thought of a female seeing us and watching us, if you know what I mean. Masturbating outdoors, Sniffing used panties, Big butts, upskirt voyeurism all the weird naughty stuff makes me ejaculate quickly but nothing seems to get me horny as such....
