Welcome to Gaia! ::

If you're expecting something like in books or movies prepare to be disappointed. It's like a workout but with extra tingles that feel better that just regular working out. And it all builds up then explodes and then you're all tired and stuff. Which is why it is usually done at night time.

No, hunny, I do that all the time

It depends on the person.
With penetration, it can hurt a little or a lot, it depends on your history as well. People who have been sexually abused in the past have a habit of reacting to sex or gynecological exams a little... differently. As for me, it hurts every time I do it with a guy, and I don't usually do penetration with women. It depends on what you yourself like in bed, masturbation is a fantastic way to find out what all you like. If you like vibrators you may be into oral sex with humming, or perhaps like toys in bed with your partner.
As Valentine said above, sex is nothing like movies and books, which is really sad, because the media puts up such high expectations for sex. It's different for everyone, but if you bleed during your first time, don't worry, that's just the "cherry popping", if you decide to loose your virginity to a guy who's less than smart, he's gonna freak out about it and probably get limp. It's gonna be a pain in the a** if your're on top, because you'll be doing all the work, if your tight, you're going to have issues with your male partners about them slipping out (oh the faces they make are hilarious), it's very tiring, and sometimes (or most of the time) you won't even be able to achieve orgasm.
Doing it with someone you love definitely makes it more pleasurable.

It's hymen getting broken, yes, but sometimes it results in bloody discharge.

Let's look past the physical aspect and I shall give you some advice. Please, bare with me. Your first time..whether a boy or a girl..let it be someone you're inlove with! Like seriously in love with! And if someone tries to tell you that you're still a virgin even if you have sex with a girl, they're wrong. Virginity is based the sexual acts not the gender, or the "cherry popping". Be sure you're ready, if someone pressures you into something ANYTHING you're uncomfortable with, its always better to say no and stand your ground then risk later emotional (or physical) damage. Sex isn't something you can easily forget about and your virginity isn't something you can take back and my absolute BEST advice (this coming from a girl who lost hers in a closet to a girl I no longer even speak to) wait until you're married. Because if you don't and you're anything like me..then you might feel guilty in later relationships if that one fails. Like you've nothing really to give them and you're love isn't true because you've done something sacred and intimate with someone else blahblahblah. Oh and most importantly learn the difference between casual sex and making love and which one your partner is after because if you don't someone WILL get hurt. Okay that's all the depressing advice from this princess^.^ if you got more questions feel free to pm me. Like stuff you're afraid to post. I'm open to any kind of question and love helping people.<3
