想知龜頭唔扯時好似右邊咁起皺紋係咪正常

χ2 淨係做BPEL啦

Bone-pressed erect length: Science MEAN 13.23 cm, Sample MEAN 14.54 cm, gay MEAN 14.52 cm, straight MEAN 14.55 cm, bi MEAN 14.42 cm
χ² = 0.0010258 << critical value = 5.99
p-value = 0.999 >> 0.05

要曲到90度先用到喎

連丁圖都未撚識揀你去用口採集數據啦

死link

出咗最終結果啦

你嗰啲仲唔好j

我指真人示範link

唔使再填問卷咪冇需要睇示範

#13 bam

MEDIAN 都有15cm 等我以為自己18cm 算好長

N = ?

科學文獻當中嘅平均勃起長度仲要bone pressed埋先有13.23 cm
真係冇度錯18 cm係好長
