for me (and please note, this is just ME.. like everyone else said, it's different for each individual), clitoral stimulation is almost too "intense" for me to handle. I've never, ever been a big fan of clit stimulation; I've always been a g-spot girl. however, last night I had my very first clit orgasm from my husband's tongue (sorry for the TMI!) and I don't think I have ever felt anything like it. I think, for me, the reason I've never had one before that is because, like I said, it is just so intense that I usually have to stop the stimulation before I actually get anywhere close to an orgasm from it. whether it's from a vibrator or whatever. I guess a good way for me to explain it is like when someone is tickling you, and it feels so good and then they hold you down so you can't move and tickle you and tickle you and tickle you until you're laughing so hard you're crying and almost peeing your pants, and you're BEGGING them to stop-- even though it does feel good. was that a good analogy? sorry if I'm not making any sense. I get to the point where it feels so good that it almost hurts, and then I have to stop. the only reason it worked for me last night was because he practically strapped me down to hold me in place (so I couldn't move away when it got "too much!" hehe), and I guess the prolonged stimulation without moving was the key to getting off.

as for the technical, mechanical aspects of clit vs. g-spot vs. other types of orgasms, I can't really help ya there. I just figured maybe if I shared a personal experience / opinion, maybe it'd give you a better view on what your friend possibly meant by "harsh."

hope it was helpful! good luck (:
