Quite a lot of people are sceptical about face to face trades, because of the risks that come with it, but that is the only way you can trade your money for bitcoin without linking it with your bank account. If you must use face to face trade, remember to meet your counterparty in a public place and you can also go along with your friend; also ensure the trade doesn' happen anywhere near your home so you're not followed.
you can as well create a thread on this board that you want to get Bitcoin from someone through p2p. But, you will send money first before anyone will send you their Bitcoin. No body will ever send you Bitcoin because you are just coming to the forum.
That is exactly what OP wants to avoid.
