Some potentially interesting advice above. Has me in tears at the thought.
Some good advice above, works for Lynne!
A minor change or to, worked for me, for you to consider?
I would shave the pubic chair completely, with a razor, wet or electric. Maybe not wet if you have had some beers! Better still get a "friend" to shave it for you. May assist with the stirrings, did for me. And stirrings actually makes the shaving easier, although you might get distracted? And, added bonus, a shaved area makes everything look larger, works for porn stars, works for me.
Pump for a couple of minutes??? FFS NO!!! Hold on, read the instructions first. The Erica (Osbon) that I had suggested pumping a few pumps, that might take 5 or 6 seconds. Then rest. Allow the body, your bits to move into position, become engorged and start to fill the tube. THEN pump again. You may get a feeling of being "stretched" in all and every angle at the same time, it starts out being a bit painful. But if you stop pumping as the pain gets to your threshold, it eases, and you can pump a bit more. You soon get used to it and, even like it, a bit, maybe? I am not into BDSM, or any pain especially where it is inflicted on me, but the pump was a weird feeling, that was quite curiously pleasurable, still is.
If you just get on and in and pump for 2 minutes you are likely to explode. It might be the best feeling ever but it might be the last feeling ever?
What do the instructions say?
Have you tried weights? Twirling? Centrifugal force assisted growth?
Give it your best efforts now, as often as you can. But don't blow yourself up FFS!
