I am almost always a grower- much smaller flaccid than erect, much bigger erect than flaccid. On the one hand, sometimes I can't believe how big my erections are compared to how small my flaccid state tends to be. On the other hand, sometimes when I am flaccid I cannot believe how much smaller my penis is than when it is erect. I therefore feel like if someone sees me naked, they have not really seen all of me unless they have seen me in both situations, when I am flaccid and also when I am erect.
One thing I have noticed that affects this, however- I occasionally go to bed with a plug inserted anally. I jerk off, fall into a light sleep for at least a few hours, then wake up extremely horny and jerk off again. After that, I remove the plug, wash it, and go back to bed. The next day or two after this process, I have noticed that I am more of a shower. Has anyone else here had this happen to them? My theory is that the prolonged anal stimulation, provided by the plug, increases circulation throughout the pelvic region and the penis for some time during and after wearing the plug.
