"I like you, but I don't know you. I'm like all men, I have to..."
It seems like the sentence is incomplete. It's missing a verb at the end, likely something like "try" or "make a move".
Here are some ways the complete sentence could be interpreted:
* "I like you, but I don't know you. I'm like all men, I have to try [to get to know you]." This suggests the speaker is attracted to the person but is hesitant because they don't know them well.
* "I like you, but I don't know you. I'm like all men, I have to make a move [to ask you out]." This implies the speaker is ready to take action despite not knowing the person well.
The meaning ultimately depends on the missing verb.
