More "outside the box" ideas
In my civy dating travels, I occasionally found myself playing an SD role, yet paying in forms of sugar that were non-monetary. For example, sometimes I would find someone 15-20 years younger who I identified as someone who was in school or freshly out of school, aspiring to enter the same industry that I work in (and have been successful in). This can be a hugely valuable set of cards to play in your favor if you can find a struggling college student or grad who sees your industry experience as valuable and can help her find a way to get her foot in the door. College has conditioned her to seek mentors, after all. And if you don't know already, single heterosexual college professors have more opportunity for pussy than a rock star in the 80's did (they might have to dodge campus policy about student dating and so forth, and social media gossip probably makes it harder these days, but the opportunity is there and my point is that teaching a female anything gets her panties wet).
But you don't have to be a professor, just experienced in your field (and all this assumes you're in a field that you can find young females trying to break into the business. If you own a retail store that sells tobacco & accessories or exotic pets you might need to search a little harder to find college grads that are looking for your specific knowledge). But let's say for example you're a doctor or otherwise work in healthcare. Do you know it's very easy to search Facebook for females in nursing school in a given city? This of course does not mean you should send form letters to all of them offering $$ for CIM (LOL). But if you see someone who seems like the open minded type, who knows what making contact with her might turn into? (Yes a doctor or anyone with a professional reputation at stake will want to be careful about going around hitting on young girls on FB, so of course use your judgment, but also remember much stranger things have happened on FB). Also if you need to protect your identity, be careful on FB (see other recent posts about this).
Most of my past experiences of these unwitting SBs started with contact from basic dating websites (POF, match etc), but FB popularity is really widespread now days so that is just one more vehicle. A lot of girls will tell you what field they aspire to work in right in their profile, whether its a dating or SD site.
This may sound like a longshot or something that only happens once in a lifetime, but I've been able to find these "pseudo SBs" on more than one occasion and benefitted greatly for it. Just remember that your work experience is probably very attractive to someone out there, its just a matter of finding her.
