How many close "straight friends" you suspect or confirmed that are bi curious ?

Updates on my friend situation:
- We rencently went to a party with our group of friends and all took some candy
- Towards end of the night, I was sitting down with him, and I told him everything about my bisexuality, the experienced I had in the past with guys, and that I kept this for myself but now believe that he has the right to know. He didnt know if I was joking or not at first, but then I looked at him and promised that I was telling the truth. I also elaborated on what is it that I like about it, the dick obsession part, how I consider this more as a kink, that it comes in cycle etc.
- He asked me some very direct questions to my surprise (eg. Did I get fucked, how many times, how did I meet those guys, did I protected myself etc.). I was a bit uncomfortable at giving him the full answer to his questions since I found them too direct and intrusive for a first open talk about the matter. I brushed the surface but, he told me that he understands and sees this more as a kink.
- We ended up agreeing to a secret code to ensure that when we say something like that, we are officially not joking. I told him that now, I have no secret for him, but that we should continue the conversation when we are sober.

It feels great to have it out of my chest. Next time we meet, I plan of apologizing for not having been fully honest with him from the start, that I was affraid of losing the friendship or being judged. I'm also thinking of apologizing for having taken advantage of our freindship by encouraging some behaviors while knowing that it was not entirely a joke on my end. Maybe i'll mention that he didnt help since he gave too many mixed signals.

I'll keep you posted if something interesting happen.
 
I used to have a workmate who at some point started to get closer. He had a girlfriend and I already had my wife. He was tall and good looking. I felt like he was trying to look for me at any time at work, like something which was growing between us, but never think much about it. One night, after some beers, we were talking about life an he suddenly put his hand on my leg and it was so unexpected that I didn't know what to do an then he quickly took it off and we both acted like nothing happened. Since the next day until now, ten years later, I still regret it.
