I agree more with the liberal Theravadian on this issue.

Foremost, we must know that the Buddha taught us how to escape from the cycle of rebirth in the 6 realms of existence. That includes rebirth as a human. Following this line of reasoning, the issue of pro creation does not take centre stage in Buddhism. So there is no such thing as human are created for the sole purpose of reproduction. Thus in Buddhism, we acknowledge that sex can also be for the gratification of sexual desire.

However, sexual desire or any form of desire is an obstacle towards enlightenment.

The Buddha did not specifically forbade gay sex for his lay disciples. However, in the monastic code, all forms of sexual gratification is forbidden. There are literature that specifically list down the various human orifice that might be involved in sexual gratification and these acts are classified as breaking of monastic celibacy vow.

Therefore I belive the fully awakened one is aware of gay sex. While it is specifically forbidden for the monks and nuns, it is not forbidden for the lay community.

Ok let’s talk about best practice for the LGBT. (personal opinion)

The Buddha is a great educator and he taught his lay disciples how to live a fruitful existence. He is well aware that gaining enlightenment is not everybody’s top priority in life. He taught everyone to be responsible for their own conduct. If we desire a good situation in life (now and the future), then we need to do good, speak good and think good.

When it comes to sex, it is generally agreed that gratification of one’s sexual desire should not create harm for oneself and others. While sex is not forbidden for lay disciples, moderation is encouraged.

Regarding sexual misconduct for the LGBT community, I think what applies to the hetrosexual is equally applicable to the gay community.

• One should not have sex with another’s spouse / boyfriend / girlfriend /partner etc. If someone is in a committed relationship, then we should refrain from sexual encounter with them. Likewise, if one is in a committed relationship, one should refrain from sex with others. In short, adultery is a misconduct for lay disciples.
• Those in an “open” relationship. The good news is that the Buddha never said we have to be monogamous. However, the Buddha did say that uncontrolled desire is bad. I guess, that means moderation.
• Sexual relation with an underage person is a misconduct.
• Rape or non-consensual sex is a misconduct.
• Sexual grooming is misconduct for a Buddhist because craving/desire is one of the hinders of enlightenment. Therefore it is bad karma to implant hinders towards enlightenment in another’s mind.
• If one is HIV+, hiding one’s status to have sex with another person is a misconduct.

I believe the above will not cover everything. They are just personal opinion formed after reading news articles and knowledge gained from discussion with friends.

I think the Buddhist perspective towards a layman is that sex is not forbidden, however one is encouraged to master one’s own desire and strive for enlightenment.
