Look anywhere in Britain or America. You see young teenage girls wearing mini-skirts and acting 'cute' as well as sexy. They hug each other, hang around with each other and spend all their time at each other's houses. If these girls (when they grew up) didn't have to work or had lots of time for themselves whilst their husbands spent most of their time at work, they would still continue to do this sort of thing with their friends. Due to Japanese culture, cuteness is more effective, but this doesn't stop them chilling with their friends whilst the husband is working late (as usual). They are just more open minded. The only reason anybody would think that they were lesbians would be if that was the culture that they had been brought up in, with more lesbians around than in Japan.
Pinson, look at any girl in america. You can't just see a girl hug another girl out of friendship and point at them and shout 'lesbian', and then go to another girl and brand them lesbian, or else you'd have to brand almost every woman around as lesbian.
And then you would get onto little boys (about 2 years - 10 years old) who kiss their mum and dad goodnight and say 'he is going to be gay/bisexual because he kissed his dad'.
The thing is, kissing and hugging and spending time with somebody is just a way of showing them that you think a lot of them and you want a friendship.
The only time you have to worry about any girl being lesbian is if she goes to another girl and slips her hand up her skirt.
Ok? Understand now?
