My first wife was okay as long as she was on the Pill, then when the doctor took her off it, she was so afraid of becoming pregnant that we never had vaginal (penetration) sex again in 13 years.
She was pretty inventive though. She had some medical training and worked for a urologist. She would stroke me up hard, and then put a condom over her two longest fingers. She would apply lots of lube, and then stroke my cock with her bare hand while she knelt beside me and pressed her condomed fingers upward into my anus. Then she would curve those fingers toward the front of my body, and massage my prostate. I would cum shortly after this double ministering to my needs, and the streams of jism would always be thick and copious, shooting quite far.
She had another trick she called 'the endless vagina.' She would stroke me with her fist wrapped around my cock, her thumb and index finger closest to my body (most guys stroke with their 'baby' finger closest to their belly). She would be kneeling behind me, her large round breasts pressing into my buttocks. She would have me dribble lube on my cock as she stroked me, then her other hand would come into play in the same position so that her right hand would stroke down my cock to my belly, then leave as the left hand began the same journey, only to leave as the right hand again began to move down my cock. This gave the sensation of my cock plunging deeper and deeper into an endless and well-lubricated vagina. I could never last more than a couple of minutes under this sensation, and then I would blow my wad forcefully away from us.
When we married we were both virgins; I never heard of oral sex until I was 25 when she came home with a copy of Alex Comfort's ' The Joy of Sex.' She taught me how to lick her pussy, and in return she begrudgingly gave me acceptable blowjobs. She wouldn't let me cum in her mouth, and expected a warning of impending ejaculation. However she developed a technique using her lips to simulate labia. She used her tongue behind her pouting lips to keep my semen out of her mouth, but her pouting lips felt like an impenetrable pussy and I loved ejaculating against them as their stimulated my throbbing glans.
