anyone used a hand pump to inflate themselves

Well,some of us just had some discussions about real inflation just recently.
Check out the archive back within the last few months.
Quick answer,Seems like most people like to do air enema,some people swallow the hose down their throat and inflate through the stomach.
Many people do water enema inflation.
Any of this is something that you have to take care doing at first.
It takes time to develop the ability to get bigger.
Much of the body training is stretching your abdominal muscles over time so that you can keep more air or water in.
I have noticed that many people that do inflation also talk about doing water bloating or eating a lot to stretch the stomach and belly muscles.
Im not sure how much the intestines can stretch in width,but Im sure that they do over time as I have noticed it with myself.Most of the expansion is probably in the large intestine and colon.
Thats just my educated guess,having myself as a lab rat.(^_-)
You can priv message me if you want to get into more info.as I do not want to go on and on about it on the Main board.
