Maybe I've just watched too many "videos". However, a woman I was with over the weekend had a big one...even bigger than me and I'm pretty big. It was fun playing and watching but got me to thinking. Didn't intimidate me at all...love playing with toys but I can see how men would wonder if it's really true that size doesn't matter as most women say. Maybe most of you only have normal\regular size dildos to get off and this is a one of situation. Interesting that I've learned from my therapist that most women prefer a regular size guy for LTR's. They like bigger guys for a fling or short term, which I've kinda found true throughout my life.
I have a cyber friend that tells me she's had big ones. One guy was so big it was uncomfortable. She prefers average cocks now after having her "big man"
You guys have no idea about us women. You're so extremely concerned about having big dicks and being curious about big is always better hence big dildo's here. Everyone is different! We all like and dislike variations of things. Some people love rough sex, some love slow sex. Some can't enjoy sex without kissing, some can't enjoy sex without pain. Some men can't perform unless she's fat or fit, some women can't perform unless there's a strong emotional connection. And all sorts of mix combo's. Some women love big dicks/dildo's for absolute certainty. Just like some men can't cum if her vagina is loose or she's boring or there's no emotional connection. Its all about discovery, learning from your own experiences - that is the fun of life. Don't rely on other peoples experiences as they can vastly differentiate from your own likes/dislikes. If you don't get on with someone then you won't see them again and vice-versa, the same thing goes for sex its the same for both women and men. I could say I love a huge 20" dildo, but what does it matter if another girl says she can't enjoy a 6" dildo? You know what I mean.
I believe that the most common device preferred among women for self-pleasure is a vibrator, which may be large or small, but used primarily for clitoral stimulation and not for deep penetration. That is also true for me, and for my circle of friends from what we've shared with each other. As far as dildos go, they look bigger than they are, because not all of it is insertable. You have to hold it, so the base-end gets counted in the size, even though it's really a handle. Your question made me curious, so I looked for a source and found that, as best anyone can tell, the average size dildo sold worldwide is 19 cm long (7.5"), while the average adult penis is 13 cm long (5.2"). Accounting for having to hold the base of the dildo, it's usable length is 17 cm (6.7"), a substantial percentage longer than the average penis, but not huge. As far as thickness goes, dildo sales indicate an average only slightly thicker than the average penis. Your therapist was probably referring to a 2015 California study by Prause, et al., of women's penis size preferences. What you say your therapist said is not exactly what the study found, but close. It also found that almost a third of the women participants had ended at least one relationship at least partly because the guy's size did not meet her preferences or expectations. In those size mismatches, her considering the guy "too small" was three times as common as "too big." The smallest model phallus used in the study was 10 cm (4"), and none of the participants selected it as being ideal. No great surprise there, even though it's only about 3 cm (a little over 1") shorter than average for a man. Sorry to the half of all men on the small side of average, but there's no market for dildos your size for vaginal use. You can find them as short as 7.5 cm (3"), but they're designed and marketed for anal use. For the other half of all men, you guys who are at least slightly above average in size, there are plenty of dildos your size on the market, and being put to good use for vaginal stimulation. Only so much can be determined from adult pleasure product market data about what sizes of dildos women prefer, because some significant number of dildos are not purchased by women for their own use. In addition to what a woman chooses for herself, they are bought by men for their wives and girlfriends, and they are bought for women for their women friends. They're bought by men for use on themselves or with other men. One of my circle of girlfriends has a habit of giving a large dildo as a pick-me-up gift after one of us has a bad breakup. She's also known for giving large dildos to anyone who lets slip that her boyfriend is small. It's a combination of cruel and funny, I suppose. I have one friend who does custom video clips as an online side business, and almost all of her clients present as male. It's fairly common for them to request to see her use a dildo, and they want to see her use ones much larger than she would choose for herself. I don't know exactly what to make of that, but just as penis size is much more of a preoccupation for men than it is for women, so also is dildo size.
