To test the limits of your belief:
Would you take on a man old enough to be your father?
Would you take on a man old enough to be your granddaddy?
In either case as long as he was trim and in good physical condition and, yes, caring also.
Not in the least interested in establishing a sexual relationship with another man. However, I could imagine a situation where it could be possible if it turned on the woman or women that I was with.
The basic question here has already been answered. A guy wants a bi girlfriend so that a Manage a Trios is at least feasible. Even so, the fundamentals regarding such a relationship is that ALL parties are equally into the idea emotionally and particularly the female who's partner is going to play. A strong bond needs to also exist between the women and the play entered into is in the spirit of entertainment and definitely not romance. If, for example, the partner's female friend has never experienced cunnilingus, or has had very little experience in that area, the female half of the existing male-female partnership might bestow on her friend, via her man, the thrill of a thorough pussy licking. It might also serve as an ice breaking event between the women. FFM relationships can and do work if all the parties are comfortable with the emotional aspect and the relationship is entered into as an adventuresome bit of playfulness. Consider all of the possiblities and the fun that can be had exploring them.
BF not interested in sex? Look at my reply to porn! Get some stills, sit him down and ask him what he thinks about so-and-so showing him an illustration of so-and-so. Go through a number of these illustrations and keep an eye on his pants. If they don't tent, then I guess you'll have to accept his word.
There's porn and, then, there's porn. Different strokes for different folks, as the saying goes and when it comes to porn one's enjoyment, or repulsion, is as individual as fingerprints. In general, however, men enjoy the visual; women the written word and that maybe because women are more discerning.
As regards to respect shown, or tenderness given and/or received, that's not the point of porn. It's basis is to get the viewer hot. For some it's intercourse, for others BJs and, as one of my favorites, cunnilingus. Now whether or not the "actress" is faking her orgasms if she does a good enough job so that I can't tell, I'm satisfied, but if she can't, the film is a failure.
One of the things I most enjoy about porn are still photographs and artistic renditions. Some of the earliest porn (not all liked, but nonetheless interesting) is the Femdom Art of Bernard Montorgueil, which treat men as the sex objects of women. He drew these pictures to illustrate his written pornography at about the turn of the nineteenth to the twentieth centuries. Before him, of course, is the notorious Marquis De Sade and following him, at the close of WWII, are renditions supposedly of enema art, but, actually, depicting woman pedophiles abusing boys (if having all manner of sex with them is called abuse). No doubt, these latter illustrations were born from a sharp decline of men in Europe and most particularly Germany following the war.
The latest, or one of the latest sets of illustrations are the outrageous behavior of women toward males in their efforts to sissify them. Amusing, but quite outrageous.
If a personality trait serves as a fetish, then that would be one of many that I have. I love women that approach sex as a fun filled adventure and like to play and be played with. For some reason though and quite in defiance of any self analysis, sadistic women who appreciate its various subtleties and indicate their amusement of them and are quite inventive in their wickedness provide me with the epitome of erotic delight. As further qualification, I'm attracted to those very special women that have the intelligence to playfully deliver their barbs psychologically as opposed to physically. Also, delivery must be done with affection and respect. So, if done properly, I'm a candidate for teasing and denial, humiliation, cross-dressing and lite spanking, where one's cheeks are warmed by a light but heavily repetitive administration.
Porn, an interesting subject. While some people, like many who have responded here, claim to like or even love porn and others claim they don't like it or find it offensive, I think that it is as individually erotic as there are individuals. As the saying goes, different strokes for different folks.
As for myself, I love the porn that turns me on and abhor the porn that doesn't. I look at it every day. I appreciate that which is real or appears so real that I cannot detect anything fake in it and am turned off by impostors. I especially like porn that depicts a woman truly enjoying the artistic tongue work of another person be it male or female. If the provider is in bondage and forced to give head, it adds an element of spice to the proceedings. One of my favorite stills is of a threesome, consisting of two females and one male. The male is lying face up on the bed, one female kneeling next to the bed holds his hard member in her hand while she sucks on his balls while the other female straddles the man's face and receives cunnilingus. In my imagination, the kneeling woman is the wife and she really wants to make it with the other woman who confided in her that she's never had the pleasure of receiving cunnilingus. So the wife has arranged the threesome so as to both introduce her friend to the pleasure of the tongue and to also become intimate with her.
That's just a sample of the porn I like. I could go on at length and what I'm trying to do, like many here have already done, is wrap my erotic notions together into a story.
