What is it like to have sex with a man?

No, I'm not a troll .... I am just a curious young woman ..... 22 ..... still a virgin unfortunately (or fortunately?). I am inquiring of other females about what sex feels like the first time .... and how long it takes before it begins to "feel good" (since I heard it's not good the first few times). Is it weird to be um, poked, down there, for lack of better term? I guess i'm not ready for it if I'm asking these questions.
