blowjobs

Ashley

So my boyfriend and I were talking about blowjobs. He told me that during a blow job you don't "suck" but instead, you lightly lick. When I asked him where he learned this from he said "Google"... I have never given a blow job but I know that is completely wrong. he is 2 years older than me, shouldn't he know how one is correctly given? I was thinking about giving him one but I wouldn't even know where to begin. tips?
