I (38F) have extremely ticklish boobs. Like, touching them myself is even a little ticklish. My husband (40M) unfortunately is a boob guy, and if given his preference, he would be touching my boobs at all times. Unless I'm literally using my full concentration to not react, though, his touching them will make me writhe uncomfortably at best. At worst, I've literally accidentally elbowed or kneed him away from me before.
Long story short, he wants to be able to touch my boobs without it being extremely uncomfortable for me. I also would like my husband to be able to touch my boobs without ridiculously overwhelming stimulation. How do I make my boobs less ticklish??
