Advice needed

I’ve been trying prostate play for a couple of years now and have never really had any significant progress but it feels really good. I rectory started using an aneros prostate massager and so far things seem to be going really well. As I’ve been able to find the time to use this massager, I’ve used it and have amazing contractions and orgasms but all orgasms have resulted with penile stimulation and not hands free. I stay flaccid most of the time and my testicles retract significantly and have a good amount of pre-cum, occasionally becoming 50% erect for a short time and amazing tingling feelings throughout my body sometimes shaking uncontrollably.

Since I’ve started this play, my prostate is constantly telling me it needs attention, all day at work, particularly when sitting down, with fluttering and a warm feeling in my abdomen. I have this sensation that I’m leaking pre-cum but there actually isn’t anything there and overall it’s a great feeling but not something I’m used to, while sitting down and doing daily office work. I sometimes feel the need to grab the arm of my chair and take a deep breathe to let this sensation subside. It’s not an undesirable sensation at all, in fact I’d love to just go into a dark room and intimate a 3 hour session if I could. I also feel some slight contractions in my stomach muscles throughout the day, finding my body occasionally jerking slightly, uncontrollably. My question, is this constant feeling a good sign and normal? I really wish I could find a solid half day to take my time and work on this more for the big O. Thanks for any advice or perspective.
