Yea so this is the first time a curious guy has wanted to actually have a relationship with me... What's the pros and cons of dating curious guys????
I did it once, even though he said he was bi, not curious (I found out the truth later). It was okay for a bit, but he was too paranoid about anyone finding out to enjoy it, and once it ended he pulled the whole "oh it was just a mistake, I'm not actually attracted to guys". Feels kinda shitty having someone just "take it back" at the end. I'm sure a lot of curious guys aren't, but that was just my small experience.
The biggest thing is probably the issue that he might not be into guys after all and if you are emotionally very invested in the relationship it might be a hard thing for you if he ends it.
