SCIENTISTS MAY HAVE FALLY UNLOCKED PUZZLE OF WHY PEOPLE ARE GAY

Among them clu:Myth 1: LGBTQ Members Make Bad ParentsMany people who are gay have lovg fai and raise happy, succsful children. The Amerin Medil Associatn is agast therapy that is “based on the assumptn that homosexualy is a mental disorr or that the person should change their ’s important to know that there is nothg wrong wh lovg people of the same genr as you. Scientists may have fally solved the puzzle of what mak a person gay, and how is passed om parents to their children.

A group of scientists suggted Tuday that homosexuals get that tra om their oppose-sex parents: A lbian will almost always get the tra om her father, while a gay man will get the tra om his heredary lk of homosexualy has long been tablished, but scientists knew was not a strictly geic lk, bee there are many pairs of intil tws who have differg sexuali. Scientists om the Natnal Instute for Mathematil and Blogil Synthis say homosexualy seems to have an epigeic, not a geic thought to have some sort of heredary lk, a group of scientists suggted Tuday that homosexualy is lked to epi-marks — extra layers of rmatn that ntrol how certa gen are exprsed. In homosexuals, the epi-marks aren't erased — they're passed om father-to-dghter or mother-to-son, explas William Rice, an evolutnary blogist at the Universy of California Santa Barbara and lead thor of the study.

"There is pellg evince that epi-marks ntribute to both the siary and dissiary of fay members, and n therefore feasibly ntribute to the observed faial herance of homosexualy and s low nrdance between [intil] tws, " Rice and his team created a mathematil mol that explas why homosexualy is passed through epi-marks, not geics. Evolutnarily speakg, if homosexualy was solely a geic tra, scientists would expect the tra to eventually disappear bee homosexuals wouldn't be expected to reproduce. But bee the epi-marks provi an evolutnary advantage for the parents of homosexuals: They protect fathers of homosexuals om unrexposure to ttosterone and mothers of homosexuals om overexposure to ttosterone while they are gtatn.

WHY WOULD PEOPLE 'CHOOSE' TO BE GAY?

"The epi-marks protect fathers and mothers om excs or unrexposure to ttosterone — when they rry over to oppose-sex offsprg, n e the masculizatn of femal or the femizatn of mal, " Rice says, which n lead to a child beg gay. Rice not that the markers are "highly variable" and that only strong epi-marks will rult a homosexual scientists have long spected some sort of geic lk, Rice says studi attemptg to expla why people are gay have been few and far between.

" Homosexual behavr has been observed black swans, pengus, sheep, and other animals, he 's mol still needs to be tted on real-life parent-offsprg pairs, but he says this epigeic lk mak more sense than any other explanatn, and that his team has mapped out a way for other scientists to tt their work.

” Many people, cludg sex rearchers and scientists, believe that sexual orientatn is like a sle wh entirely gay on one end and entirely straight on the other.

CAN SCTN MAKE STRAIGHT MEN GAY?

My last post scribed a populatn of mal who nsir themselv heterosexual, do not label themselv gay or bisexual, chew volvement wh the LGBT muny, are often married or romantilly volved wh an oppose-sex partner, and who engage sex wh mal or exprs the sire to do so. Due large part to the popularizatn of the topic the btsellg 2005 book On the Down Low: A Journey to the Liv of 'Straight' Black Men Who Sleep wh Men, [i] Lato and Ain-Amerin men are the primary subjects rearch wh non-gay intified MSM.

One of the earlit studi, "The Bisexual and Non-Gay Attached Rearch Project" om the early 1990s, found that participants engagg same-sex sexual behavr but not intifyg as gay or bisexual scribed themselv as “kky, ” “normal, ” or “jt a guy.

WHY ARE THERE GAY MEN?

Siar fdgs were found throughout a seri of terviews wh non-gay intified MSM prepared for the Centers for Disease Control and Preventn 2004. In tally, the men terviewed reported that if sexual activy between men was anonymo, experimental, ocsnal, or if substance e was volved, the act was not “gay.

IS MY HBAND GAY? SIGNS OF A GAY HBAND

There are doubtls many reasons for this, but one recurrg paranoia among many I’ve met (all of whom were men, out of tert) is that I’m gog to tell them that they’re gay. I’m not sure how the guys thk homosexualy works or how you end up beg gay, but one thg I n nfirm is that ’s not my cisn.

Bis, even if I did thk they were gay, ’s certaly not somethg I’m gog to brg up when first meetg someone, given how ’s a) irrelevant, and b) none of my damn don’t feel the same though. Homosexual members of society n unfortunately expect to regularly be challenged, sctised and nmned by belligerent type who are seemgly nvced that homosexualy is a “liftyle choice” issue has e up aga (for what is possibly the 12, 456, 987, 332nd time) for several reasons. There was a recent study that suggts homosexualy is lked to the X chromosome, so is therefore geic, ie herent, not a choice.
