Understanding Aneros-less Super-O's: Looking for some insight and explanation

Well, I had the most amazing experience (ok, I'm still sort of new at this) this AM. After a night session during which I fell asleep, and a morning 1 1/2 hour session with a "good morning" reward, I was reading about 2 hours later, lying down and inadvertently (maybe not) brushed my nipples and immediately felt that intense pleasure sensation "down there" that I have noticed over the last month. Up till now, I had checked to see if the nipple sensitivity was something I could initiate prostate/perineal pleasure with, without the Helix Syn in. And it didn't. But today, I felt immediately that I was passing into that pre-O phase. I ran upstairs, stripped and began an 2 hour experience that was so intense. Though I have what I believe are super-O's for several months, I never had that wave of pleasure pass all through my body, and feeling it (fleetingly) in my spine, my chest and even in my legs. And the incredible tranquility that followed was close to ecstatic. It was clear to me that the intense pleasure leading to the orgasmic phase was lower down than the prostate--in the anal canal. And it was directly related to nipple stimulation. When I stopped the stroking, brushing, flicking, the pleasure stopped and vice versa. I could knock myself over the edge just with the nipple work. Down there, I felt a rotating tickle in my anal canal. When I compare the perineal sensations of today's aneros-less session with my very pleasureable Helix sessions, it seems clear to me that what I've been experiencing in the last months has been mostly the anal experience (I'm not dissing it, they are wonderful). Those sessions have mostly been "do nothing" sessions, with little full pulling upwards or prostatic stroking and little thrashing about. So later today, I re-inserted my Helix and made sure that I got the prostate, and yep, it was a different experience. I was able to get both prostate and anal sensations, and it was very, very good (even though I think I overdid my sessions--3 sessions, 2-3 hours each in the course of 14 hours).

So I'd like to hear from my aneros co-travelers about the following questions
1) do I have to do some more work to re-wire my prostate now that my anal sensations seem to be the prime site of pleasure for me
2) Should I continue using the nipple stimulation (I guess I'm "worried" that it's a "crutch" that I'm using, since it works so well for me) or work on truly hands-free sessions and concentrate on my prostate?
