I make others very aware of what i do/don't do for them if that's suspected.
You know my ENFP and it's likely that he thinks i kiss his ass / agree with him just to agree. I've had to inform him that he's one of the few who i almost completely respect and i don't throw out compliments or agreement where it isn't due.
Other friends have recently said "You have to say that because you're my friend" and i inform them that i don't have to say anything nice for that reason and i wouldn't say anything nice for that reason alone.
Most people can't be expected to understand without a bit of an explanation. There is usually too little contact from people who encourage intensely where they feel it's due. There is also a complete obliviousness to the fact that we will tend to zero in on what we are encouraging, unless a negative gets in the way of our promoting or is brought to our attention.
Personally, i counter it with a lot of little remarks like Geoff mentioned. With a lot of people, i start off on the remarking foot.
You're a very squishy person
(not in an INFP way, which i'm hoping you understand based on previous conversations) and that's a pretty dominant trait. You're also a bit brash and that shows here and there. Just make sure you become aware of yourself and don't just forcefeed females positivity. You're more of a whole person that stands out when the brash comments start to roll here and there. It'll work to your advantage.
A common problem for most men of various types is being nice vs. being an asshole. That isn't how it works. There's no switch to flip and i'm sure you know that. Too many men think they need to be really far to one side of the spectrum or to bounce between the two, bipolarly.
Be neutral. Lean with it, rock with it - so to speak.
