Quoting James' Mommy Anna [PSM]:" it took a LONG time for me to have one... its almost like the guy has to be shaped a certain way lmao... ... [snip!] ... it but we'd have to be on the couch with me sitting on his lap toward him... id have to like grind on him to get it to happen"
I've read on a few websites that you need a lot of pressure on ur g spot to get it going, also read that doggy style is a good way to achieve one. I guess being on top and me being in control is something to try. Just tell him to sit still and dont move lol. :-)
