I tend to fall for straight guys. Certainly not intentional, but you can't really control who you develop feelings for or care about. The first time, I was pretty obsessed. It was the first guy I came out to, and fell very very hard. We worked together a lot, went out to drinks, dinner, etc. I majorly confessed my feelings for him, and in hindsight feel mortified that I did it.
Fortunately, he's very understanding and he really cares about me, so our friendship has only gotten stronger and we're best friends now. Now he teases me about what he'd let me do to him.
Currently dealing with another straight guy who I care about a ridiculous amount. He's actually told me he loves me like a dozen times. I've only initiated those words once, otherwise I just say, "I love you too". He's always been very affectionate with me (hugs, kisses, high fives, etc.) until recently. He's been awkward around me lately which has been pretty upsetting. I've never confessed any feelings for him, but he's probably assuming I have them. I'm not sure things with him are going to work out as well as my other friend.
