I've been on Prep since late March of this year. I got on right before a break up where we were mostly monogamous with a little play together a couple times a year, but always safe. I'm 39 and since I started having gay sex I've used a condom 95% of the time, unless with a partner. It took me a few months after the break up and on Prep, but in June I took my first load with a guy who was Poz and undetectable on Meds. Since then I've only used a condom once this summer and i've had A LOT of sex. A lot of amazing, mind blowing, load taking sex. My sex life has never been better, or hotter. it's gotten to the point that if a guy says he only plays safe, it's almost a turn off. Luckily there's so many guys that I meet now that are either poz and on meds and undetectable, or negative and on prep that i find more people interested in raw than not.
I will say that getting through that first 3 month check up was a little nerve racking, but once all my tests (hiv, syph, etc) came back negative...I knew I'd just keep taking more loads. Having that fear gone has really let my inner pig out, and I'm quite happy about it. :-)
