Can I be 100% alpha w a 6 x 5.5 dick?

Do guys rate their own overall SMV? How much does dick size factor in?

I know most women prefer bigger than average.

Its more than caring what women think about SMV (still relevant imo) but its also about being able to do less positions with a smaller member, and throwing a hot dog down a hallway as most sluts have gotten pounded by monster cocks so sometimes i feel like im resigned to mediocre sex... except w 18 to 20 yr old 5 ft 99 lb nubiles, i exclusively approach those now but havent laid one in 6 months, 3/40 of these 8.5+ girls in the last month message me regularly

sex feels much better w these girls but still please advise regarding Dick size affecting SMV

If SMV wouldnt exist if we lived in a world where men lost all sexual desire, as Patrice said, making women overnight 2nd class citizens, then its women who decide what our SMV is, (the concept of sexual would be irrelevant so...) and my research, which makes me a scholar on this by now, says 8 and above is 'big' for sure, 5 and below is for sure small by hundreds of anecdotal party sluts/ 'normal' girl accounts online, girth > lenght obv

Women prefer bigger than average and makes me feel sexually infereior to most of my 'competition/ confident broad shouldered tall guys in the dating pool w big dicks' as height AND broad shoulders do correlate to d size, eg, shaq would never have a micro

women are disappointed by my dick when they see it bc im 6'3 200lbs of muscle w a 6 inch, average at best, wang

finally , the best TRP advice i recall is that women have a check list of 538 items a beta must have - 6 figures, 6 pack, 7 x 6 minimum dick, but its strictly a mechanical thing for me as it feels like im fucking a bucket of warm water

please advise
