a guy tries to take the girls virginity and it's not really working no mather how much he does that.that guy is also a pervert/playboy wierd guy but handsom or something like that or a manga with a lot laughter (comedy).......tnx guys....

an example Momoiro Heaven!
Hana Yori Dango
Kaichou wa Maid-sama!

Oh Momoiro Heaven!

I can't offer something exactly among the three works you've mentioned, but the following do have similar beginnings, but something does happen eventually --

Chou yo Hana yo (I know it's josei, but it's so ridiculous... but it's smutty later on soooo... be warned!)
Kiss/Hug - maybe not so funny... it's a little more serious, but I mean the girl has never been in a relationship before, and she's a little freaked out with men so...
Private Prince - she's not a virgin, but she's single... he (on the other hand) wants to get into her pants ASAP... (again, josei and smut)

tnx u so much,,,,,,=D
