androgynous faceA while back, I explored one of the very few studies that tested Stoller’s observation that “true” MTF transsexuals, which we now recognize as exclusively androphilic MTF transkids, are “avoidant”.  That is, that though they have intimate relations with their boyfriends before SRS, they refuse to use or allow contact with their pre-operative genitalia.  Stoller (and others) held that non-exclusive androphilic women would not be “avoidant”, but would find pleasure in the use of their male genitals prior to SRS.  Now a new study explores this behavior.  But sadly, since it comes out of Europe, where they believe that age of onset of gender dysphoria, early or late, is the most important typology, the study failed to explicitly report avoidant behavior by sexual orientation.  However, I hypothesize that Stoller is correct, and that even though we don’t have explicit data in this new study, we will see a direct correlation with the percentage of exclusively androphilic transwomen in the two onset age categories and avoidant behavior.  Data is reported in the number of transwomen for each category except for that reported as percentage:

Sexual Orientation vs. Age of Onset
Onset                                                 Early         Late
Androphilic      N=                             54               20
Non-exclusively Androphilic         53               78
Percentage Androphilic:                51%            20%

Avoidant vs. Age of Onset
Onset                                                Early           Late
Avoidant           N=                            38                15
Pleasure                                             34                47
Percentage Avoidant:                     53%             24%

Note the essentially identical percentages of exclusively androphilic transwomen in each onset category and the percentages of avoidant behavior?  Thus the data supports the hypothesis perfectly.  This of course is not definitive, since we would really like to have seen the direct comparason, but if the numbers had been wildly different between them, it would have supported the null hypothesis.  The null hypothesis still cannot be ruled out… but seriously?  Seriously?

It has been my personal observation, from talking to MTFs, during my entire lifetime, that “avoidant” behavior is near universal in transkids, but very rare in “late transitioning” transwomen.  Such late transitioning transwomen have very often been sexually active with women, married to women, and have had children.  Obviously, the easiest way to have sired children is to have had vaginal intercourse (penile penetration).
