Curious about something
I’m 56 and married to a woman. I starting to really experiment with things however. I have been jerking off to more and more gay/trans porn lately and even more recently started playing with my ass. I started fingering myself in the shower and have managed to squeeze two fingers in but have also gotten obsessed with my plunger handle. I stick it on the shelf in the shower and lower myself onto it trying to get further and further down the handle. I seem to be stuck at about a 6” depth and am hitting what I assume to be my prostate. My cock is hard but seems to be a chubby hard on instead of my regular 6 and a half inch usual stroking length.
My question: is it normal to have a different kind of erection while having anal play than while masterbating?
