I'm into penis size humiliation big time but there's a lot of artificial stuff out there where you can tell the actress/cam girl is simply trotting out the scripted SPH she's been paid for. I am much more turned on when it is genuine.
Coupled with this fetish of mine is the fact that I am a bit of a geek. Thus I have listed below published scientific literature regarding female sexual satisfaction that supports the theory that size matters:
Firstly, vaginal orgasms would appear to be more intense than clitoral orgasms: "vaginally activated orgasm (VAO) were associated with higher orgasmic intensity compared to clitoral orgasms…Women who preferred reaching orgasm through masturbation to partnered sexual activity had lower orgasmic intensity"^1
And penis size is indeed an important factor in attaining vaginal orgasm:"Women who prefer deeper penile–vaginal stimulation are more likely to have vaginal orgasm"^2
Meanwhile the poor little guys who've been told they can compensate for their lack of size with tongue, toys and fingers would appear to be selling their partners short:
"Vaginal orgasm is associated with vaginal (not clitoral) sex education, focusing mental attention on vaginal sensations, intercourse duration, and a preference for a longer penis"^3
"vaginal orgasm consistency [VOC] was associated with greater sexual arousability from deep vaginal stimulation but not with sexual arousability from other genital sites."^4
"When both sexual activity categories are examined in tandem on a population level, women's likelihood or consistency of partnered orgasm is associated with penile-vaginal intercourse duration, but not with foreplay duration. In contrast to the assumptions of many sex therapists and educators, more attention should be given to improve the quality* and duration of penile-vaginal intercourse rather than foreplay."^5
*and the quotes above show quality is enhanced by a longer penis
And despite the narrative that size is not important to women:
"a considerable percentage of the women respondents attached substantial importance to the size of the male sex organ"^6
"The smallest penile size was rated as less attractive than three intermediate sizes. The largest penile size was not the most attractive, but received higher scores than the unaltered and smallest penile size."^7
So a bigger penis is more likely to give a woman a more intense orgasm and these orgasms are more likely to make the woman happy:
"women's dyadic adjustment+ is independently predicted by greater vaginal orgasm consistency… Women's sexual satisfaction score was significantly predicted by greater vaginal orgasm consistency, frequency of partner genital stimulation, and negatively with masturbation… Concordance of partner vaginal orgasm consistency estimates was associated with greater dyadic adjustment…The findings suggest that specifically penile–vaginal intercourse frequency and vaginal orgasm consistency are associated with indices of greater intimate relationship adjustment, satisfaction, and compatibility of both partners"^8
+Dyadic adjustment is a process with consequences that can be identified with the rate of couple's problematic conflicts, interpersonal tensions, individual anxiety, marital satisfaction, coherence integrity, and collaboration about important problems
So there you have it from the scientists ladies and gentlemen: getting fucked deeper and longer makes the ladies happier.
