When I was young, I read every book, magazine, or article I could get my hands on that discussed sex, the female body, or was medical related (usually just skimming through to get to the good parts). Many would mention that women often need stimulation other than just vaginal, mostly focusing on the clitoris and g-spot. Most men's magazine articles stated to make sure the woman always cums first. So that's what I always tried to do. I never minded because it just meant more of me going down on her and/ or fingering her. Which I love doing both of.
The first girl I ever had sex with was also my first long term relationship. It didn't take me long to figure out she couldn't orgasm from just PIV, but needed other stimulation. So most times during sex, I would eventually make my way down to finish her off before I would penetrate her and get myself off. There were times that were just quickies, or she just wasn't in the mood for a full course meal that she would subtly skip the foreplay and lead me straight to the fucking. It was always her choice if she didn't want an orgasm.
So every sexual relationship after her, I approached sex and orgasms the same way. I always got her off with my mouth or hands first, then sex (or whatever) after. Then I met my wife. Again, it didn't take me long to figure out that she enjoys PIV better than anything else. She craves a penis in her vagina when she comes. Her preference is hard and fast, almost exclusively. When we are going at it like this, she cums fast. Like 2 or 3 times before I have my first orgasm. I'm not bragging or some super stud, it's just how she's wired. She still enjoys me using my hands and fingers, and can easily cum this way, but it's not her first choice. Oral feels good to her, and she is capable of cumming eventually, but she has a mental hangup about it. She's afraid she's dirty or smells or doesn't look good, so she doesn't let me do this very often. She is the only woman I've ever been with this way.
