Where I grew up there was little diversity. No real subcultures or "minorities". Hence when I get chatted up one day by a guy guy in my house, in my own room no less, whilst being the only two people in the house... My paradigm changes. Suddenly I'm not talking to 'just one of the lads' as I knew it but someone who saw me as a potential sexual partner. Now I'm not saying there was anything inherently wrong with it but I was entirely unprepared. To that point I don't think I'd had that many offers from females and surely none I'd turned down and definitely none which were an automatic no (I fear that sounds really negative but it was my honest response, I'll let you judge my intentions and foibles to your hearts content). In that moment I had to say no whilst panicking about coming across as homophobic and in the realisation that unlike most girls this guy could force the issue if he so wished and I would be at a severe disadvantage. I think I gave a couple of stone and about four inches in height in comparison.
Yes it's basic but it obeys the base male rules of
Can I eat it?
Can I kill it?
Can I shag it?
I was ill equipped for the situation and until homosexuality becomes just another facet of society it will worry people. The odd thing is that the instinct is to fight the very thing necessary to solve the problem.
