Diary of an involuntary celibate: PART 1

It's been 2 years since I last had sex. Yes it has been that long. Not because I lost interest or because of one health reason or the other, truth is I just lost it. I wonder if I ever had it in the first place. I have doubted myself more and more with each passing day. I figured out my problem a few months ago. I couldn't seem to seal the deal, I was always stuck in the unwanted zone of friendship, the initial flair that attracted the ladies seemed to die out after a few dates, actually after the second date. I just became boring and what promised to be a blooming romance died even before it could smolder.
I couldn't seem to trace the origin of my problem though the last lady I dated was not really the origin, I however noted the events that led up to my dating her. Her name was Esther, and before I dated her, I was on a mini draught. I just broke up with my high school love Oyin. We had dated for about 3 years before she found out she was too good for me. She got a job at one of the biggest audit firms in the country and moved to the high brow areas in the city. We both lived in the same town but seeing each other became a burden. So she dumped me for no reason and my friends Victor and Hassan scouted Esther after 3 months as a suitable replacement. Esther was sweet and lovely and the sex was good but I found out I had forgotten how to woo a lady or seduce her. I never had to seduce Oyin, she loved sex and was very open about what she wanted and when she wanted it. I and Oyin had sex on the 2nd date of our official dating and it had been very frequent after that. With Esther I faced the rude shock of how unskilled I was at seducing the opposite sex . Most of the flings I had while I was with Oyin were either her friends or girls who saw Oyin and wanted to steal me away from her. Oyin had a way of making me look more desirable. No, I wasn't a saint with Oyin but I was discreet in my affairs. Truth is I really missed Oyin and wanted Esther to be her or at least the sex should be like Oyins but it wasn't and I didn't know how to ask, never had to ask with Oyin and I guess I never really learnt the tricks.
So its been 2 years since my last sexual relationship with Esther, the one and only sexual relationship I had with Esther before she left town and I never heard from her again and now I am at girlfriend potential number 13 and I think I'm beginning to genuinely like her and now I am getting myself prepped for the disappointment of failing to seal the deal yet again. What is a man to do?
