It sounds like you might be a "real hottie." Men naturally jump out their butts over hotties. More than a few men--me included--have made fools of themselves over good looking women.

From what you say here, I don't necessarily see a problem in all that is going on. If these men are expecting favors in return for what appears to be kindness that is another thing entirely. If no special favors are expected, I think you should just say: "thanks for the wine." But, if they are trying to get you into the sack against your desires, there is a problem and you may want to start politely refusing gifts.
