Hi LWH,
I’ve used a CTC for about 1.5 years now and continue to use it on a regular basis. I also own an LAPdist which I use occasionaly. I have the CTC set up in my sauna - so, if I am using the sauna I pump. If I choose to pump but not use the sauna I use the LAPdist.
The CTC 50 pulse/min has little or nothing to do with masturbation and a lot to do with healthy circulation, in my opinion. This is especially true if you acclimatize your unit to pumping at say 3 inches of Hg (mercury) and work your way up to say 5 inches of Hg. Why? - increased vacuum increases the reactionary force against the pubis which can throttle circulation - message here is take it very easy.
As for cost, if money is a serious issue (and these days it generally is) I would go with the LAPdis as it is a good product and comes equipped with an accurate vacuum guage (provided you keep it dry). However, you’ll learn to milk the tube when you pump with either the CTC or the LAPdist which helps migrate your unit down the tube over time and helps with circulation. Also, it is very important to kegel when you pump.
As for tube size and source of supplier, I have had good results with LAPdist tubes because they have a very generous flange that abuts the pubis and that helps distribute and normalize the reactionary stress. Since you mention a 5.7 inch girth at the base, a 2-inch tube will probably work fine and give you some room to grow. It’s always nice to grow out of a tube! Don’t get too large a tube or you might suck your nuts up into the tube as you pump - not life threatening but a rather rude experience that you will only want to do once.
If you decide to pump, use a good lube both at the tip and at the base, be sure to wrap so as to protect your circ scar if you are circumcised, and shave your pubes so as to get a good vacuum seal.
Hope this Helps,
MrTiPS
