To be clear, I'm not saying that every gay man or straight/bi woman needs a massive cock to enjoy sex. Obviously that's not true, and some people find that painful. But, on the whole, we are still a bunch of monkey-brained idiots who will never get over our collective obsession with genitalia. And, in my opinion, abstinence is the best of course of action for men with extremely small (as in less than five inches) penises. Not because everyone needs a huge dick, but because most people are extremely cruel and disrespectful to men with small penises and immensely dislike small penises in a sexual context.

It's not that it's impossible to find a person who will tolerate (not prefer) your dick if you're lesser-endowed. Indeed I've had such a partner in the past who was fine with me. But the potential reward of a loving relationship is far outweighed by the immense personal humiliation and social stigma that comes with having a small penis. You risk not simply being rejected for being small, but being widely mocked and ridiculed by your social circle if your size ever becomes known. People respect you less, and you become the butt of jokes. There's a reason people constantly making small penis jokes, and that the phrase "small dick energy" became a phrase. You are treated as less of a man, and your partner is viewed with pity.

It is simply not worth it.

Furthermore, you're also inherently forcing your partner to settle for you if they're not asexual. As I said, not everyone loves huge dicks, but NOBODY genuinely enjoys tiny penises. So you are essentially sentencing your partner to a lifetime of inferior sex because you do not want to die alone. That, in my opinion, is selfish.

In short, all of the social shame and sexual distaste associated with having a small penis means you are simply better off lying to people that you are asexual and removing yourself from sex entirely. The fact is that no gay man or woman will ever truly PREFER (not just tolerate) your body if your penis is small unless you want to be humiliated or cucked, and everyone knows sleeves/strap-ons are just cheap substitutions for the real thing. In kink communities you are excluded from dominant sexual activities centered around penis size, and are generally not eligible for MFF threesomes the way better-endowed men are. The only time you are ever preferred is to be humiliated and degraded, and that is bad for your mental health.

IMO we just need to accept that and try to focus on other things in life, or try to date people who are asexual. Having a small penis is simply too much of a sexual and social handicap for a relationship with a non-asexual person to be worth the stress or guilt.
