Shane said most of it already. As for the 'father-son talk'; it mostly goes like this:
Father: Son, we need to talk about sex.
Son: Sure dad, what do you want to know?
Father: Aww ****! Well, let's get a beer.
As for the situation itself, I've come pretty close, even though I wasn't a virgin. I was about 18, she was about 26 at the time. A good friend of one of my house-mates. She was pretty aggressive about it all, and it was very clear that this one was about sex and sex only. Sure, we had great times and talks in bed in the morning, but we definitely never 'went on a date'.
The only thing I can tell you was that it was a GREAT experience. If you're open to learn, there is much to be learned. There is no reason why she should have 'great expectations'. If you somehow know she's got an impressive sex drive, she'll probably know you don't know about yours. That being said, 'impressive' is a rather subjective term. Who knows what it means in this situation?
As for 'losing your virginity', much can be said about the subject. There'll always be people who think it's a valuable commodity of some kind, and there'll always be people (like me) who think virginity is vastly overrated. Don't confuse love and lust. These two things are highly enjoyable in any kind of mix of the two of them, but they can easily exist without each other.
Losing your virginity is nothing special. There are no fireworks. You don't feel any different afterwords, you don't become some kind of depraved sex-animal when it's done. But that is just my OPINION, and the worth of your virginity is something only you can consider.
If you go for it, remember two things: Sex is about mutual satisfaction but satisfaction is not equal to orgasm. It's not binary. If you both have fun, you're good. Second: Ask questions and talk about it, because that's the only way to explore her and your own sexuality.
Just go slow. Don't jump straight into sex. Start fooling around first, get to know each other's bodies well so you'll learn what techniques work well. A lot of positions look easy in porn or in movies but they aren't. Shower sex is awkward and (possibly) dangerous, for example. Your first time will not be the best sex you ever have. Real sex is awkward and messy and needs to have communication to be successful. Perhaps you can look up some guides in how to perform basic manual and oral techniques. The first woman I was with couldn't tell I was a virgin because I was well prepared.
Also, another key is to TALK. Be open. You don't necessarily have to tell her that you're a virgin until after, but talk about preferences, what you'd like to try, mutual kinks, etc. That will build sexual tension. The longer you build that tension, the better the sex will be in the end. Also try not to go overboard on yourself controlling that tension, otherwise you'll get death grip and your first time will last two hours with no one climaxing, like my first time. Too short is better than too long, since you can just wait 15 minutes and go at it again.
I can't believe no one has said this yet, so I'll say it; just becasue she talks a good race, doesn't mean she has any more actual experience than you do. I've got a niece that on Facebook looks like an 16 year old nymphomaniac. She's actually an insecure virgin that thinks she has to look and talk like a porn star in order to be popular. She's never met her father, so I try to be a positive influence in her life. I can't get it through her head that "pretty" and "sexy" are two different things. Sorry, I got carried away there. I think those that have said talk to her and be open with her are dead on. Who knows, she might just be acting that way because she thinks that's what YOU want.
she might just be acting that way because she thinks that's what YOU want.
I'd rather think she's a slut who's going to teach him a thing or two. It's the romantic in me.
Sacrificing virgins is a long standing tradition amongst proper sluts.
Exactly.... "Sacrificing".... Never saw the attraction to virgins though....
Well the OP said that she has a strong libido. The last two women I were with both had strong drives, but neither really flaunted it. You could be correct, but we don't know the nature of the situation.
