@izzythepush,
Hawkeye is trying to promote acceptance of behaviors that can cause serious or permanent injuries or even death--and he wants these acceptable as legitimate legal sexual behaviors between consenting adults. But, in fact, the types of things he refers to are not sexual contacts, they are forms of physical abuse. That he finds such things sexually arousing is quite beside the point, abusive physical contacts are not sexual contacts as sexual contacts are legally defined.
I knew someone who engaged in "consensual" asphyxiation with a partner, for purposes of sexual arousal. Unfortunately, on one occasion, it went too far and the partner died. Did it matter that this was allegedly the outcome of a consenting activity between two adults? No. The person I knew was arrested, charged, prosecuted, and convicted, for causing the death. And it wasn't regarded as a "sex crime--it was considered a reckless act, without sufficient regard for the welfare of another, that resulted in a death, and it was prosecuted under the murder laws.
Hawkeye is trying to claim that physical abuse is the same as sexual contact, simply because abuse is sexually arousing for him, but he's making an illogical connection in that regard. They are two separate issues--legally. Which makes his concerns about the legality of consenting to physical abuse way off the topic of this thread.
This thread, as you understand, but Hawkeye and BillRM don't, is about the issue of consent regarding
sexual contact as it is defined in the sexual assault/rape laws. Those laws have nothing to do with physical abuse, or consent for such abuse.
