There is a saying in AA:
Secrets keep us sick...
or conversely
Secrets make us sick....
The sick part is turning to a lot of bottles of spirits to wash away ones 'problems'...
Trust me, that doesn't work... No really it doesn't - yeah sure last month or so I was back on the saddle - so to speak, but honestly did that solve anything? No.....
The secret: You're gay, your single, your clearly waiting for the right man to come down the pike - clearly you ain't into free love type sex, this ain't the 1970's, its the 21st century.
Church.
Do you have a faith? If yes then by all means do (or don't) find a church of people who share the same faith as you. This might help to that effort:

Do NOT use your faith as a weapon of mass distraction. Or destruction or a weapon - period. Its not a defensive weapon, it is not an offensive weapon. Faith is about love, and God and something I don't know - not a weapon.
They cheat - fine, you're a liar - which sin is greater?
Um neither.... (In case you forgot).
You are lying... and that isn't ending well for you.
Yes, perhaps you are not really interested in random sex with random people. If that is the case then say that - don't say 'I'm a good Christian' - Lord knows plenty of people have used that line to justify all manner of evil. This just isn't who I am - so be it, they will hate you for not being promiscuous.
Once they get used to THAT idea, then blow them away with.... Oh and I'm gay too... Let them do the linkage in their head about all the stereotypes about gays having to be promiscuous.
This holding it in about your sexuality isn't doing you any favors, if anything its causing you to question yourself and start down a fools journey - other than drinking problems away, but thinking that if you find the right woman....
No Sir, there is no right woman - you ain't wired that way... And the longer science keeps plowing this subject the more convinced science is that it biological and as immutable as the color of your skin your height, your extra nipple (if you got it) hard wired into the body.
Now you do not have to take a full page ad out in the Sunday newspaper, but do by all means not hide who and what are. You don't even have to say 'I'm gay' say something like, 'I'm waiting for the right guy to come along.'
BTW this setting you up with people, this shoving their sex lives down your throat by talking about it all the time... I think its time you talk to human resources to please define what sexual harassment at the work place means in this area.... It may be an eye opening experience.
