We enjoy crossdressing because we have conditioned ourselves to? and it always has a sexual connection?
Sorry, I started crossdressing at 6 and have done so since then, enjoyed the sensations it gives me, since then. I wasn't forced to, I enjoyed it before any idea of conditioning could occur. I have had periods of up to two years where I didn't crossdress, but that conditioning didn't succeed longer term. Conditioning, nup! It's something else.
Sexual connections, oh sure my fantasies are maybe different to some. So what. Sure I had periods where dressing was pretty much a sexual act, but it isn't now, and it wasn't pre-puberty. So yes it can be, but not necessarily.
The more you try to put this business in a box the more incorrect you're going to be. And generalising about anything is a sure way to get a very skewed view. We're all connected in a way but we're all very different. Maybe we need to spend more time appreciating that.
