I used to be fairly flexible as a younger man and I can get pretty close these days even with no warm up stretching or anything but my main questions would be, what stretches do you use to help self suck and also how do you maintain erection. Im more of a grower than a show-er and I'm finding it's hard to even get an erection while bending like this. How do you guys do it let alone maintain one? I know with just a little more flexibility through stretching and a maintained erection I could at least get the tip in but I'm having troubles. Any advice appreciated thanks in advance
