This is possibly TMI, but it's been intreging me and I kinda want to know the answer, or your opinions on why, or simply whether this is just normal...
When I've not got my binder on I have almost no sensation in my nipples, I can grab the nipple and twist it around over 180degrees, or pinch the nipple and areola really hard, yet it hurts less than pinching my earlobe. Apparently, and from what I found out when touching another guys nipples, they are usually much, much more sensitive than mine.
I always put this down to when I was about 10 and on holiday, I refused to wear anything other than swimming trunks in the pool, and wore nothing on my top half. I suppose I was at the stage when the dredded things were just starting to get ready to develop. Climbing in and out of pool my nipples got rubbed on the concrete, and by the end of the week they were scabbed, possibly a little pussy and very sore. Since then I've just assumed that this was the cause of my lack of sensation in them, but then when I'm wearing my binder and I run my hands over my chest (it's kinda weird and vain I know, but I seriously can never stop doing it

) I can feel sensation in my nipples which I've never felt before.
Is it just something simple like that the nerves are all squished together so there's more in one place, meaning more sensation there, or something like that? Or is it more psychological, as in they shouldn't be out there attatched to the fatty lumps so I refuse to associate with them and feel them, but when they're where they should be then I can feel them?
I hope this makes some sort of sense.
