Are you asking if you can reroll your character under communism?

Somewhat, but two points:

1. attractiveness is not material condition, standards of beauty change over time fairly significantly. Your physical looks are getting refracted by societal norms into attractiveness.

2. these are not material conditions marxists bang on about

No, the Marxian term of material conditions is tied to the labor’s relation to production. For example, the labor wage relations necessitate that you sell your labor to earn a living, without which you cannot survive and will perish, and this in turn dictates your material conditions, and those of your family, and those of your community.

the fuck are you asking for? You're the Ultimate Communist.

If you're assuming these are physical traits you are born with then thats just a very problematic way of thinking.

Is dick size a material condition?

no, these are just physical traits

minus luck

Not really. Luck isn't a real thing. It's a perception of our past and largely a cultural framing device for your feelings on events that occur in your life. You could argue that some people are lucky by being born into a specific family, but that's kind of a philosophical issue as it implies that that person may have instead been born into another family as if by some form of divine neonatal cleromancy.

The rest of these for the most part are not material conditions, but are factors primarily affected by your material conditions. Health and appearance are largely affected by genetics, environment, and exposure to certain compounds. Someone raised or living in an area with poor air and water quality or with little access to healthcare is likely to experience more negative health effects than someone from a cleaner environment and access to healthcare and these can affect appearance greatly. One's intelligence, skill, or dexerity are heavily affected by education, quality of home life during childhood, level of practice, healthcare, nutrition, pollution levels, and other external factors.

These external forces are largely the same for groups of people rather than individuals, which is where Marx largely applies the concept of historical (or dialectical) materialism.

The German Ideology may be helpful for further study.

I think I misunderstood your question

seems to me that your material conditions affect your stress levels, confidence, clothing, and cleanliness, all of which will have some impact on attractiveness. and doesn't it make sense that looks, dexterity, intelligence, and health are all affected by the material conditions of your childhood and adolescent development even in the face of putative genetic factors. nutrition, noise, pollution, access to physical exercise and leisure time to do it in, etc.
