Nah. There is one factor and one factor only in sexual attractiveness: confidence. People who love themselves attract sexual partners regardless of other factors. There are many ugly fat small dick guys who consistently get laid simply because they believe they can. More advice:
(1) Try this exercise: make up a lot of reasons why you can get the dick you want (rather than making up a lot of reasons why you can't). Strap on the Law of Attraction, because it is a sexual big tool.
(2) Don't get down on yourself for preferring guys with big dicks even though you yourself have a tiny dick: instead, accept that you love big dicks, accept that you yourself are under-endowed, and accept that you are incredibly sexual attractive. Notice the emphasis on "acceptance:" once you embrace acceptance on the mental plane, your mouth and anus will accept big dicks in the physical. (But if you continue to reject yourself, others will continue to reject you.)
(3) As for real world tactics: Have you ever tried letting your prospective lovers know upfront that you have a small dick? That gets rid of the guys for whom thats a deal-breaker, and attracts the guys who don't mind or who prefer them.
(4) You will likely have to deal with your share of tiny dick fetishists, guys into SPH, and kinky people who associate dick size with sexual hierarchy and sexual roles -- make a decision as to whether you can tolerate/enjoy that or not; there's no shame either way. Fetishism, SPH and roleplay can actually be turned into an erotic platform for attention-getting and self-love (ie, "embrace the stigma" as a tactic for getting what you want). All kinds of personal qualities can be sexualized or demonized by the erotic marketplace: but it's your choice whether to go with the flow or head in another direction; make the choice that makes you happy.
(5) Given that your dick is small, you probably won't be a top. You may need to accept being a bottom, and you may need to focus your desire on total tops if you prefer monogamous LTRs.(But who knows? Some bottoms may want to collect cum deposits without the hassle and pain of getting their manpussies stretched. Just as a lot of people don't like small dicks, a lot of people don't like big dicks, but the porn industry will never tell you that.)
(6) There needs to be a "small dick pride" movement. Maybe you should start it. Ask porn producers to explicitly sexualize small dick men. Dick comparisons get me off, so I love watching big dick tops destroy tiny dick bottoms; I hate it when the bottom wears a jock to cover up the fact he's got a teeny pecker. Long live micro-penises! I once had a longterm fuck buddy with a 2-incher -- he was a big hunky jock otherwise, and I totally got off on making him suck my cock and lick my balls. I think millions of other guys would find that scenario really hot.
Hope this advice helps you get more bang from the buck for your teeny weenie!
