Yeah, I actually was with virgins back in my youth, or so it seemed. Not by intention; I was just a boyfriend kind of guy, not a ‘fuck for sport’ kind of guy.
First off – you better be of legal age or you need to leave my blog. Assuming you are, I suggest you really make sure she is ready for this. If you care about her, you will push back on her advances, multiple times. That is what I did with the girl I cared about most when I was young and when she finally took that leap, there was no “he pressured me” guilt. It was her decision.
Then, be extremely sensitive to her needs and emotions; if she gets mad at you at any point in time before, during, or after, including weeks later – it is your fault and you need to see it like that. No matter what it is – suck it up and just be there for her.
It’s a big decision to part with your virginity as a woman, so don’t take it lightly. Besides getting married and having kids, it is one of the biggest hurdles any woman takes in her life. Be sensitive to the idea you could fuck her up for a long time if you don’t handle right, especially afterwards, both immediately and for months after.
You – as a man – define yourself by how you handle this type of thing for a woman. Do you want to be a good man, or a shitty one? Don’t take it lightly; you have a few opportunities in life to measure the type of man you are, and this is one of them. So man up, do what is right, and if you love her and she loves you, then proceed. If you know you are not staying with her a year from now, walk away and let her give that gift to a man she won’t regret later.
To answer your question directly – physically, you need to make sure she is very wet and you use lube, or a ton of spit, because it will hurt no matter how big you are. The most she has felt is likely a tampon. So, dick and pussy need to be very wet, then lay her on her back, ease in, and let her adjust. Wait. Back up. Make sure you have a home or hotel with a bed, and not some car. Make sure you have hours to hang with her afterwards, laying there. She needs this closeness and so do you, even though you may not know it.
It won’t be spectacular the first time for her, no matter what. If you want to make the experience positive, I suggest you make her have an orgasm before you have sex. The easiest way you can probably do this is via wet fingers doing circles on her clitoris (see diagram) until she cums.
Stay persistent for a decent amount of time; you will know when she cums when her knees fold inward and she shudders for a good sustained amount of time (similar in length to when you orgasm, but a bit longer). Clit orgasms tend to be the most short-lived ones.
After that, then proceed with intercourse. Wet, use your fingers to part her lips, and go in slowly and let her adjust. Go slow at first and pick up from there.
Good luck. I hope you can take this opportunity to set forth a path as the right type of man. The world needs more good men. Make sure you are on the right side of this decision.
