...Continued from above...
Ideally, you'll get her nice and turned on, and her sweet juices will start to flow (mmm just writing that sentence is making my mouth water and crave to be pressed up on my lady's sweet glistening pussy lips) and once she's starting to feel the mood like this, you should keep it going for a while, keep touching her, playing with her nipples, kissing her, talking to her about things that turn her on, licking her... ideally you'll be able to get her off once during foreplay to make sure she's extra ready for penetration.
Then at that point, she's ready for penetration by your "ginormous peener"... and this is where lube comes into play. As I said, some pussies are wetter than others. If she's a super wet girl, then she's probably ready to go as is. If she's not the type who gets as wet, then grab silicone based lube, I recommend Pjur, it's the best. You can use silicone based lube with or without a condom, and it is silky and lasts a very long time (doesn't get sticky like water based lube, and water based lube just sucks in general, I don't recommend it ever). Even if she is the super wet kind of girl, lube will not hurt at all, so lube yourself up, feel free to apply some to your crotch and her crotch too so when she grinds her clit on you it will have a slippery buffer to slide around on... At this point, I recommend slowly easing yourself into her. I love to drag this process out as long as we both can stand... it builds anticipation, and watching her eyes roll back into her head when you give her just a little bit more, and then a little bit more, and then a litttle bit more... is just incredible... I mean, if you have a huge cock, why not take advantage of the advantages of having a huge cock right? Give her your dick slowly and at her pace, feel free to go even slower than her pace as she'll be aching for you to go deeper, which is a better state for her to be in as opposed to going too deep and hurting her and halting the progress by her wincing in pain. If things are going according to plan, she'll have probably already cum a few times at this point. I know in my experiences, there is often that moment where I'm teasing her with half of my dick and then eventually she is just begging me to put it in, and I'lll wait a few moments, and just surprise her with a deep thrust (I only do this when I know she's ready for it) and if she hasn't cum yet, THIS is the moment where she literally loses control and explodes. That's my favorite. Especially when she's held back her orgasm up until this moment and decides to finally let it go... unf...
Then there is the question of what kind of wet is she.
This might sound confusing but it's true. I know of two different ways a woman is wet. And I'm not a sex health professional or a doctor, I'm just an educated and experienced civilian amateur who loves pussy and pleasing women. The first type of wet is the wetness that is sticky and creamy, its slimy and thick, and it tastes like heaven. This is secreted from her vaginal walls as she's aroused. This fluid acts as an amazing lubricant, and it allows for very high sensitivity to be felt. Then there is the second type of wetness, this second type is more watery and thin, and is not as slippery, it has a slightly different aroma and it comes from her para-urethral gland (no it is not pee). This is what comes out when a woman squirts, or ejaculates. But she doesn't need to be a squirter for this fluid to appear, it can come out in small amounts without her "squirting" like you see in porn. I've experienced a squirter and I love it, the sensation of her releasing all over me with the warm juices is simply amazing, it bathes your dick and shaft in warmth and drips down your balls, and its just, wow. Now when a woman releases this second type of wetness, the more watery thin type, it can have a downside as it in a sense can wash away the thick slippery creamy wetness that was inside of her in the beginning. You can still keep fucking, and it won't be a big deal, but when she's squirting or just "gushing" a lot of this fluid, in my experience, the sensitivity goes down a bit, and she can eventually become rubbed a little raw as this fluid isn't as good as a lubricant as the first type of fluid. Yes, you can keep going as is, but theres a good chance she'll be a little sore when you go for round two, or she might even need a break for a few hours. So once she's squirted or gushed this fluid, and you can feel the wetness change from slimy to watery, at this point you have two options. If the session is coming to a close, then just finish up as normal. But if the session still has 5minutes or more left to go and you want to continue fucking for a while, then pull out for a moment, apply some drops of silicone based lube all over your dick, and then rub some on her pussy lips and clit too, maybe even rub some on your pad of skin just above your dick so her clit can have a nice slippery place to rub itself on, and then continue fucking... The sensation will be better for you both, and you're taking precautions to keep her pussy happier so that when you're done, and decide its time for round two, you can annihilate her pussy all over again and she'll be rolling in pleasure all over the bed, all day long, cumming and panting for breath, not knowing what hit her. Which in the end, is what it's all about right?
I know this isn't the answer you were looking for. And probably don't care to be hearing this stuff especially from another guy. But I know what I'm talking about, and I know what's best for you (haha but seriously) so just give it a chance. I hope this helps
