Yes Gay culture is over sexualized and the fact that sexual orientation is the primary biding factor does make any correction of this phenomenon difficult. To blame this on youth and try to cover up by stating that heterosexuals do it to is simply a low-brow 'race to the bottom'[not a pun just a widely accepted ephemisim] type argument which adds nothing. I do not claim to be an angel and I have slept around as well and do not regret it, but I am not seeking to justify my excesses by saying look over there, he is doing it too as it is childish
I find the fixation of Gay men (who are pro-free love for everyone), to be the most unhelpful and their response of don't force your morals/religion ect on me ....... to smack of hypocricy as they are the same ones who preach that you are not a real gay men unless you sleep with lots of other guys. I don't believe it's just horny young men at all thats BS, older gay men need to address their own trauma from being brought up in a society which condemned them for just being gay, not perpetuate a continuation of unhealthy relations between our fellow gay men.
I don't subscribe to the argument that as men we are biologically pre-disposed to seek a mate/partner, who is better than the one we have already have, or a biological imperative to seek as many sexual experiences as possible. I also find the generalized response of many experienced gay men to dismiss anyone challenging the notion that to reduce our fixation with hyper sexual behavior very troublesome.
Conversely I am certain that all the studies which show the benefits of healthy sex life, prove that periods of self imposed celibacy unless it's for medical reasons. I am also very aware and acknowledge that there is a sizeable minority who are not engaging in problematic behaviours of which are defined as those of which inhibit elements of our daily functioning and may even be definable as an addiction.
We are bombarded so much that many gay men develop a sense that their sexual prowess is the one and only identity they have, then we wonder why as we mature and loose that peak prowess that for many our mental health, relationships suffer, our careers become stunted and the incidences of substance abuse to cope with being part of a community that only values sexual prowess. I am not saying this as sour grapes as I am having a healthy sex life myself. Many gay men learn to engage in sex to get anything and everything they need, for many not out of any other motivation than to feel they are able to negotiate through the minefield of the Gay scene which perpetuates the idea that you must be heavily engaged in lots of sex or be considered less desirable or worse.
If Gay men developed self esteem and confidence to participate in the gay and wider community and that opportunities to develop friendship and support networks were more prevalent, the high risk involved with rampent hyper-sexuality would be far less prevalent. This is because men need an outlet to challenge and to at least some of the time successed in their endevours, many of these behaviours such as hyper sexuality, substance missuse and other risk taking outlets generally available to heterosexual men, which in a sizeable minority would start to diminish.
A healthy sex life and being sex positive does not mean being a slut, that is unhealthy and is not what being sex positive is about.
