It's interesting how these topics always migrate at an alarming speed towards homosexuality, even when it's not connected with the original point. It's interesting how certain posters who claim to oppose homosexuality bring it up time and time again and refuse to stray far from the topic.
As regards certain methods of intercourse, there are just as many heterosexual couples engaging in them. Moreover, some homosexuals do not engage in them - one cannot assume two gay men are going to have sex the way one expects them to. Also, the use of condoms can easily remedy any hygenic issues.
At the end of the day, I don't want to know what anyone is doing behind closed doors and in their bedroom. That's why it's behind closed doors and why it's their bedroom! So for me to insist that I don't want someone as my neighbor due to their sexual preferences means I care enough to know what's going on in the first place! Rest assured, there are countless straight couples engaging in unusual, unconventional sex acts (some of which I REALLY don't want to know about). How does one ward off the heterosexual couples from living next door to them when they aren't privy to which specific sex acts they engage in?
