well...seems like these thoughts are screwing you.
it's all in your mind. affraid of your smell?, get some really expensive cologne for men.
you probably don't have friends that are girls in your life at the moment. like everything... you have to get used to it.
i suggest.... maybe going somewhere, bar or something, where talking to girls, mainly waitresses/bar maid would be an ease, no pressure. a few questions about something to do with the bar or their service of drinks/food is always a good way to start then go on to general conversation.
but i do hope you know every woman is different so...you have to be aware of the way they talk, what they wear or if they are carrying a book or magazine etc etc paying attention to their clothing or something will give you a bit of detail to start talking about their interests.
to actually talk to them, you need confidence...thats about it.... there nothing to lose, give it ago. plus...i find out that some/most men always wish that a girl would walk up to them and try to pick them up or start a convo....although funny, it's the reason why some men are still single. This rarely happens and if a woman does that it might not be the clean women your after...if you catch my drift.....
if you want to stay away from them....thats fine...but you'll be missing out....i can tell you that.
if your under 18 and can't go anyway besides mac donalds or arcade stores then...i can't help you.
