This pregunta is about sex so don't read it if tu don't want to!

Well-well. Harry and Ginny (the tattoo thing kind of gave it away, since Ron didn't go OMG how would my sister know that), Ginny and Dean, Draco and Pansy, Cedric and someone (I don't think it's Cho), maybe Ron and Lavender, but I'm really not sure about that. No, rather no. cruzar, cruz out Ron and Lavender, there was something like Ron was peeking at Bill and Fleur possibly to collect some tips on snogging. Now in that case it's unlikely that he got farther than besar and hugging with Lavender. fred and George might have, but I don't think the target was the quidditch team.
Back to the generation before: Snape and Lily, Lily and James, James and half of Hogwarts, Sirius and half of Hogwarts (not necessarily the other half, there might be an intersection of the sets), Bellatrix and the whole 16+ Slytherin house including Rodolphus and his brother, Lucius and quite a few Slytherin girls (possibly Narcissa too, but if so, for Narcissa Lucius was the only one - I can't exactly picture Mr Malfoy marrying a girl who's been taken por somebody else too, plus they even loved each other), Snape and some misceláneo girls (not to many, after all he was into Lily). And I'm sure that Sirius and James didn't let Lupin and Pettigrew graduate a virgin either. However, if those two did have sex, that was definitely with the agency of James and Sirius.

Ron and Lavender Brown possibly. Most likely though would have been Sirius as well as James.

James and Lily, definitely. Also any other couples from the Marauder Era -- it was the 70s. This very definitely includes Bellatrix and Rodolphus Lestrange, por the way.
About the rest... I don't know, interesting question. I'm thinking not too many.

I personally dont think Snape died a virgin. I think he and a certain ginger " got it on" one night.

Not at Hogwarts but, I dont think Voldemort died a Virgin either. I think him and Bellatrix had one on one meetings, and they pleasured eachother. Him using her only for greed, and to feel wanted. Her obviously cause she loves him.

harry n hermione were alone in a tent for like months, i am just saying. fred and george with the quiditch team too.

none

Draco and pansy, come on, she do anything to be with him, can't blame her though, he's hot!!! LOL,,,

I think it happened, but it wasn't too common. Between the house-elves, teachers, and students that prowled around at all hours, I think it would have been near impossible to find a quite spot and not get caught.

I know I'm goin' to offend several fans por my answer, BUT that's my thinking. I always thought this couple pretty serious and they MIGHT have sex. Sorry, if it hurts you---

Ginny and Dean!! OOUCH..

I think very few of them, but i could be very wrong.... but i know ron and hermine - <3, harry and genny = <3 and thats all i can think of right now...

Sirius, James, Fred, George
- anyway. maybe Ron and Lavender too,
and Draco also

I think it's James and Lily ...
o Sirius with a gorgerous girl ...

Just maybe :)

Cedric and Cho seem like a strong possibility to me. tu know, before he was murdered.

Sirius and that girl checking him out at the Defence Aaginst the Dark Arts OWL possibly, he seems like a player :)
Lily and James <3 amor them, but I still feel bad for Severus

U U nevermind

Molly and Authur. The had Bill in their, like, seventh year.

james and lily definately, he was tht into mischif tht havin sex @ hogwarts would totally b an optsion for him
sirius prob did cuz the book described his as hot
im sure remus did 2, not so sure about snape, unless lily got alittle 2 drunk once to know wht she was doin and who she was doin it with
