John and I were married many years ago, and both of us were virgins on our wedding night -- sure a little heavy petting before the marriage -- but that was all. In the first few years, it was pretty much just missionary position, but I rarely found it pleasurable and never had an orgasm from vaginal penetration. John's cock is pretty small, certainly by porn standards, though it was many years before I even saw pictures that showed me there were plenty of bigger dicks out there. I've never cheated on him and I'm pretty sure he has been faithful to me, but sex has not been a major part of our lives together.
I'm not a prude, and our transition to exclusively oral sex took place a long time ago. I am willing to accept and indulge in some new experiences, but swallowing cum and ass play or anything involving pain are all off the table. Though John loves to eat my cunt, and will devote a lot of time to pleasuring me, I rarely get so totally absorbed in it that I feel a climax is on its way. By being so quiet and restrained, John probably does not realize just how much I enjoy it. Never been a screamer, and am just not comfortable with vocalizing any guidance that would drive me over the top, so I guess I share the fault of not maximizing my pleasure. Maybe if I had masturbated more while a teenager, I'd know my body better, and improve my satisfaction.
That being said, I am an expert cocksucker and drive him wild, between pleasure and pain, using my tongue and teeth, to have John squirming and squealing whenever I take his rod into my mouth. Many times, I suck him past the point of no return after only a few minutes. I choose not to squeeze the base of his cock, to delay the orgasm, though I know he'd love to extend the torture and pleasure for much longer. Nor do I ever try to suck his softening cock back to hardness, and go for a second load of jizz.
On reflection, I may be unfair, as he's probably eaten me out for more than forty-five minutes before I start to go down on him, and sometimes it's just fifteen minutes before he blows his load.
