yeah - happens frequently. when i was younger it weirded me out and i thought i was a freak. then later, watching porn, i discovered that it is not all that rare. it seems to be increasing in frequency. i have wondered about wearing a ring to keep them down and out but am afraid that it might injure me as the boys seem so determined to pop inside. sometimes when jerking or having sex they are very sensitive and when they slide in and out it is exquisitely pleasurable. i have even pushed them in myself to get that feeling and fondled the bulge on the outside. cool to have someone discussing this.
