Water pumping. can't seem to pump without red spots
I have a cheap, gauge-less pump that I have tried in the past with air and received little visible results, but plenty of red spots. Using it with water instead seems quite a bit more effective, but I run into the same red spot issue. After having read plenty of threads here, I know that it is very difficult to tell the level of vacuum without a gauge, but it seems like many pump with water instead of air and do so effectively. A gauge can’t be used while water pumping anyway, correct? How is this done safely?
I’ve tried to water pump and use seemingly low pressures with trial and error, but it seems like one session one day for a given amount of time and (seeming) pressure that nets little discoloration can result in very bad visual results another day with the same time and pressure. I’ve made enough mistakes this way to where there is significant shaft discoloration, and it seems to match up visually with the small blood vessel networks in the shaft skin. Thankfully I don’t seem to have any real erection issues, but I feel like issues will be inevitable if I continue going this way. I have some girth goals that I feel like would be well served by regular, longer, low vacuum pump sessions, but I don’t think I can afford to keep rolling the dice like I have been.
I’m a healthy 30-something that exercises regularly and has a good diet, so I think it unlikely that my blood vessels themselves are weak.. Does anyone else here have problems with red spots/broken vessels and pumping?
