ZahofCalif,
First, Welcome to Gayspeak.
No sir, it is
not only you. I fear there is a lot of players out there, guys who are looking to score another booty call or to add one more notch in their belt.
I devised the 30 day no sex policy as a means to separate the wheat from the chaff. I make it clear that there will be a snowballs chance in hell that a potential mate will get in my pants the first month we are 'dating'. That usually sends a majority of the ones looking for 'just sex' scurrying back to their rat's nests.
During the course of that 30 day period, conventional dates should reveal more about the guy and his intent. Those few 'conquers', guys who have a serious desire to add you to their list of 'I did that' will tip their hand in subtle ways.
There are some - rarer cases - that are real good and can keep up the act. So a few can get through.
If you are meeting guys through bars, clubs, Grind'r then that may be the problem. Nice guys, guys who want serious relationships usually give up on these scenes because they, like you, discover a world of sex-junkies who are all about the hook-up and not about substance.
So where do you go to find men? The library, work, AA meetings (If your not an alcoholic then that mayn't work for you) , the grocery store.... All of those natural places that people tend to go to in their life to do other things - there are men out in those places, some of which are single and gay and most likely will like what they see (you) and most likely are more sincere.
I understand that LGBT centers are 'safer' places to go to to meet quality LGBT. IDK, these are a relatively new invention and their isn't one in my local area.
Betrayal of trust is a serious matter and it does thing to the person who has been betrayed. I'm sorry to say that you will carry all of that distrust and other emotions for a very long time. The best you can do is try to turn it around and use it as a tool to sift through people you meet and hang with to remove the chaff from the wheat.
If it is serious enough of an issue, I would suggest therapy to isolate the root cause(s) and to figure out ways to work with it, and get your own personalized set of tools to deal with it in a manner that causes less harm.
