I purchased the Bathmate 30 Xtreme and have been using for 3 weeks. noticed that i definitely saw some expanstion in girth with little length. I do 3 - 5 min sessions per day. noticed swelling just under the head shortly after finishing a session. goes away after several hours. also made the mistake of putting too much pressure on during each sessiopn. so my questions are the same as all beginners: how much pressure to apply? what is the best routine for length and girth? there was a mention of a video but the link was broken and it would not display. desire to carry on a pratical discussion with real users experience.. thanks for this platform
