I had a woman I thought was mine. I had her for so long I thought that thing could change the way we felt about each other.
I am a highly sexual individual and I certainly have a much more developed sexual appetite than your Normal person. As such I took matters in my own hands for years. Take just regular everyday masturbation for example. I since I can remember masturbated everyday. I may come home from a date where I had sex and then masturbate. I would at times rub one out right after having had an orgasm from rubbing one out.
This hunger for sexual pleasure developed into other parts of my body and I explored. I used to insert ice cubes into my anus. I would insert toothbrushes and other things. I used to take handfuls of my own cum and shove them in my mouth or do like a headstand and cum on my own face. I wanted to do these things with my girlfriends and then my wife but while we were dating just getting to have sex was hard enough. Then after we got married, during the newlywed phase when we were supposed to be having lots of sex, we had almost none. Arguments ensued and resentment both ways I am sure. I may not have been very good at sex during this period. I may have made her feel isolated or something and therefore "not in the mood". I am not sure but at any rate the point I'm trying to make is that it wasn't an environment conducive to sexual exploration or openness. So I kept my desires and activities secret.
