For me, it started with crossdressing. I went at it pretty hard and have
2 closets filled with women's clothing. I had to have breast forms, so I got A, B, C, and D forms and all the stuff you need to wear them. For me it was mastectomy bras. Well, those kind of bras aren't very sexy, well most of them. I have a 4 or 5 that are nice.
One day a voice popped into my head. I guess that was my noise. "Instead of spending all this money on fake stuff why don't you see if
you can grow them yourself?" I scoured the internet and found Natureday and then this site. The voice said, "See?"
Now the voice, my noise speaks up on two accounts. They are from equal points of view. They are both important. Obviously I like having breasts and want them to be the size that I want, a B cup. There is very much an arousal thing here. It arouses me to have them and to play with them, and the sensitive nipples are great. So sex and growing breasts go hand in hand.
Now, the crux of the biscuit. When my libido stalls to nothing, well it's kind of a deal breaker. Yes, my nipples become very erogenous and
when played with simultaneously during sex, the orgasms are much enhanced. Until the pecker doesn't care anymore. I've tried nipple orgasms, but while the feeling that it could work is there and feels really good, it ain't happened.
My noise speaks up, "Hey man, it ain't happenin down there and I don't like that. This is unacceptable!" So I listen. I recently had to take a break from the PM for this reason, but am back on it now. I'm going to take JulieTG's advice about off time.
The noise in my head is not the only one I listen to.
