You can do several things to get better in bed.
First of all, understand that, unlike men, sex begins hours - days even - before it reaches the bed for most women, depending on what you do. And teasing is probably the skill that is most appreciated by women in terms of turning her on and getting her up there. Every move you make will turn her on, little by little. The fact that women talk about sex around you, means that you're doing something right.
Second, learn about your own sexuality. Look into ways to either control yourself, or control your own pleasure. Like, the first thing I wanted to find out, when I was about three years old or something, was how to make that orgasm last longer. Omg it's too short, ahem, the orgasm I mean... (Ooook here comes the inevitable d length jokes... I guess deserve it sigh...) So, from a really early age, I wanted to learn how to make it last longer.
Long story short, I didn't really find a solution to that, but I did find out how I could last a helluva lot longer in bed. Part of that has to do with getting used to (instead of desensitizing yourself) going beyond the orgasm, so to speak, so you can just continue one orgasm into the next, and the next, without stopping and without getting soft. This is a learnable skill. For now, I'll just end it there, and encourage you to find books on the topic of that, and how to better please women. And not just with your d, but also with your hands, lips and... your words. Man, your words are powerful. And powerful men use them to command people around them. And if she's the least bit submissive (and most women are deep down) she'll gonna want you to command her and man-handle her. That shit turns on women like mad. But don't overdo it (or if you do want to overdo it, discuss some safe-words with her first.....)
On this journey of introspection (ok, I'll admit it, that's just a fancy word for make jerking off into a science), I learned a great many thing. For instance, to this day, I still consider it my biggest achievement (if you can call it that) to be able to cum without touching it, using only my mind. That... is control. I mean, you might not need that level of control, but if you want to last longer, it actually helps.
Now to the big caveat. I learned to last for hours. And I thought I was this GOD in bed. Except, if you last too long, that's not good either. Women started complaining that they got sore and stuff like that. Eventually one told me directly that, "Man, sometimes I wish you'd just pin me down and dump your cum in me real fast. I love quickies!" That, and the fact that, while I learned to care so much for how she felt in bed, that I often forgot myself. Man, that's when I really started enjoying sex; when I knew I didn't have to impress her anymore, but that I was freed from having to last the entire evening, and instead could just focus on enjoying myself with her.
Anyway, tl;dr: Grab some books on the topic. Watch this porn video: Nina Hartley and Sunny Lane - How To Eat Pussy Like A Champ. I mean it. Really do! It's about the only actual porn vid I will recommend for its educational value. I think also are some PU books on the topic of being more commanding in bed, using authority and domination, and your voice, to turn women all. When you've got all that down, then who cares if you just lasts for 10 seconds? When you can literally command her to come for you!
Hope this helps!
