Not "trying", I am saying that before the time I was 21, I was already well versed in virtually all aspects of sexuality including oral and anal intercourse, tantra, various styles of massage, BDSM, most fetish practices and lots of medical/biological/physiological/psychological knowledge of what, why and how. I had been sneaking into BDSM and swingers clubs in N.Y. when I was 17. I read voraciously anything I could get my hands on that was in anyway related to sexual pleasure. My girlfriends were very satisfied sexually.
Unfortunately, I didn't learn to apply myself to the more emotional aspects of my relationships to the same degree until I was first cuckolded, which occurred in my early twenties.
So while I was quite adept at providing incredible sexual experiences for my girlfriends and knew how to take care of most of their body, the one area that I was woefully inadequate was in how to take care of their hearts.
In fact, that was usually the reason that my relationships ended. Once the initial passion ebbed, the girls would begin to feel that all we really had going for us as a couple was great sex.
While I didn't feel that way then, I have to admit a debt of gratitude to the man that made me a cuckold.
