If by violently you mean passionately then I understand. But if you kiss him violently then you would kind of attack him with a kiss or the kiss would be sudden and unexpected. However if you mean passionately, then you put your heart and soul into this kiss, like your life depends on it. It's usually used to show how much you love your bf/gf and how much you need them/want them. Close your eyes and just give out everything you've got when you kiss him. Hold him tight but with care and lose yourself with this kiss. Soon he'll find himself understanding what you mean and he'll lose himself in the kiss too!
*If this isn't what you meant, then don't listen to anything I said ;) *
