I find your "Three-Way Love" scenario.....intriguing. Particularly if both men should be bisexual. That said, I am something of a newbie here, and do not have the male partner to bring to You in the triad. Still, i suspect You have any number of us eager to do Your bidding, and fill that role.
Being the dependent, infertile husband in "Wheels of Love" has its appeal, if You might consider some variations on the premise. While your frustration would be a given, I would enjoy it more if the husband is impotent not because of castration, but perhaps because of psychological factors.
If either of these appeals, I look forward to discussing with You further.
