I hope the lady enjoys spending time with me, but depending on how you define that label, there are a couple of significant limitations on the quality of the BFE.
1) Available time. I usually can't get away for very long, and a 3 or 4 hour tryst is rarely possible. Treat her nice (beyond mutually enjoyable BCD), with respect and conversation, etc.? Sure. Something more akin to a traditional date, longer and where public time is half or more of the total time together? Not easy.
2) Me. No, I'm not in the typical self-deprecating "God I'm so lucky these women will even talk to me" mode we see too much of around here. But I'm an extreme introvert and my social skills and interpersonal awareness are not strong points (one lady categorized me as "Asperger's personality type"), so I may not always be a lot of laughs. And even beyond that, a BFE -- just as with a really good civilian date -- probably relies on compatible personalities to a significant degree. I'm not going to be every lady's cup of tea, just as any particular lady is not going to be every guy's cup of tea.
I try to make an encounter pleasant and fun, not just in the sexual sense, for a lady. I want her to have a good time as well, although I typically don't bring champagne or even wine.
I like her a lot, or I probably wouldn't see her frequently, and I try to act accordingly. But what are the minimum requirements for something you describe as a "BFE"?? I don't know, so I certainly won't claim to provide one.
And why label it? It makes sense for the ladies because they're marketing to us, but I don't anticipate trying (or succeeding) in persuading any of the ladies to spend money for a date with me.
