Let me tell you about the hottest experience of my 30+ years on this planet.
It started four months ago when I had a bad head injury that left me heavily concussed among other things. Once my concussion started to heal, my sex drive skyrocketed unexpectedly and wouldn't slow down. A bit later, I was diagnosed with hypersexuality due to a brain injury.
Now, I've always been a very shy guy. My sex life has been quite vanilla, I've never really spoken up about fantasies or anything like that. Not only did my sex drive explode, but I'm way more open to new things, my shyness has gone away about most thing etc..
I've been with my wife for 5 years (we'll call her Lydia), she's also the reserved & shy type and our sex life had gone downhill for the past while. She's also fucking gorgeous - long dark hair, dark eyes, pale skin, glasses, tattoos, an amazing set of tits and an ass that turns heads.
When I first told her about the hypersexuality thing, she didn't really believe me and thought I just wanted to get laid more often. Eventually she finally agreed to sit with me and have a real conversation about it and heard me out. She was fascinated by the effects and how much my personality has changed since all this started. We talked about different ways to spice up our relationship, different things we wanted to try, we talked about fantasies we were afraid to share etc.
During our talk, she asked different questions like if I was into BDSM, if I had any 'kinks' or if I had ever thought about having a 3 way with another girl. I'm a straight man, of course I've thought about it - she was surprised to hear my answer, but I was more shocked that said she was really interested to try too.
