Physiology & Medicine / Can the menarche be seen as an indicator of pubertal onset?

« on: 02/04/2017 12:03:12 »

The sexual scientist Ray Blanchard wrote in one article:

"The average age of menarche for American Caucasian females is 12.9 years (Herman-Giddens et al., 1997). There are various other indicators of pubertal onset, however, which usually appear before menarche."

Blanchard, Ray et al. (2009): Pedophilia, Hebephilia, and the DSM-V. Archives of Sexual Behavior, 38 (3) 335-350 (quote page 335)

Typically the beginning of the Tanner-Stage 2 of breast development is seen as the beginning of the puberty of girls.

Does anybody know if there are other scientists besides Ray Blanchard who see the menarche as a possible indicator of the onset of the puberty of girls?

Did scientists 100 years ago saw the menarche as an indicator of the onset of the puberty of girls?

Are there any discussions in science if the menarche can be seen as an indicator of pubertal onset of girls?

Personally I see the beginning of the Tanner-Stage 2 of breast development as the beginning of the puberty of girls. Does anybody here disagree with this point of view?

Thanx in advance for every help!

Quotable articles would be great because I am writing an article about that topic.

General Science / Re: Is BDSM linked to "child sexual abuse"?

« on: 22/08/2016 16:28:18 »

In the meantime I found one important study:

Richters et al. (2008): Demographic and psychosocial features of participants in bondage and discipline, "sadomasochism" or dominance and submission (BDSM): data from a national survey. Journal of Sexual Medicine, 5 (7) 1660-1668.

"In Australia in 2001–2002, a representative sample of 19,307 respondents aged 16–59 years was interviewed by telephone."

"In total, 1.8% of sexually active people (2.2% of men, 1.3% of women) said they had been involved in BDSM in the previous year."

"Table 3 shows that for neither men nor women was engagement in BDSM significantly related to having been sexually coerced ever or before age 16 years."

Women who participated in BDSM Sex: 13,6 % coerced before age 16 years

Women who did not participated in BDSM Sex: 13,3 % coerced before age 16 years

Men who participated in BDSM Sex: 5,2 % coerced before age 16 years

Men who did not participated in BDSM Sex: 2,6 % coerced before age 16 years

So it seems "childhood sexual abuse" generally is not the reason to participate in BDSM.

General Science / Is BDSM linked to "child sexual abuse"?

« on: 22/08/2016 07:39:00 »

Hello,

I have two questions:

1) Are there any studies who compare how many % of BDSM-practioners were "sexually abused" in childhood and how many non-BDSM-practioners were "sexually abused" in childhood?

2) Patrick Holmberg wrote: "There is a long history of psychologists attempting to explain BDSM sexaual activity through the lens of mental illness including Sigmund Freud who argued that masochists were often people who were abused during childhood and were now attempting to gain mastery of this trauma by replicating it in a controlled environment (Connolly, 2006)."

is there any scientific literature about what is the truth in this issue/the speculation of Sigmund Freud?

Thank you very much in advance.
