A bit of context here. I came to Canada from a culture that was free to talk about sex (among friends of both gender) but overall was sexually repressed (ironic since my ex-birth country gave the world Kama Sutra) when it comes to the acts. Also, there was (not any more I guess) this general lack of access to internet porn. Before 2004, I really did not have a proper understanding of what all the sexual acts meant let alone entailed.
Now, in Canada (2004) when I saw all the goodies here, one thing stuck out is how a woman gives blowjob down on her knees or rather assumes a position below the man while performing the act and the way it generally ended with it being one sided. To me it felt exceedingly degrading. It wasn't the act (which now I am desensitized to) rather the perception of power in that the porn industry had imbibed the male gender. I don't know if I am the only one, but given what women (generally) in porn industry have to do to satiate the myriad of sexual desires of viewers comprising of males (mostly) and females, my respect for them (and women in general) rose over the years.
Sex and all its acts form a part of power play in a relationship and if I have a son/daughter (especially the latter given we do not yet live in an egalitarian society) then I would do well to teach him/her the importance of not being taken advantage of.
