It depends on the nature of the attention from the men, and what those men look like.
When you run pickup bootcamps, for instance, you suddenly discover it is about 10x easier to get laid than usual because the guys are usually decently cool, and the women notice that they are coming to you, you are in some sort of official / advisory role over them, you are instructing them on what to do, and you are an authority. The women don't know the dynamic... they don't realize you are having them approach girls... they just pick up that these guys are deferring to you as some sort of authority. They read the body language, voice tones, etc. You start getting AIs like crazy and the girls you open just blow open for you.
On the other hand, if you go out with a group of buddies and sit at a table and everyone is laughing and joking around as friends, that makes it somewhat easier to approach, but not as easy as when you are the clear authority figure.
There's an attainability element as well. e.g., go out with a really cool buddy, just you and him, and shoot the shit with each other in a bar for while, having a great time just chatting with each other, and when you come up for air and look around you will usually notice a couple of hot girls standing around you preening themselves, who open readily as soon as you talk to them. Sometimes they will get impatient waiting for you to notice them and may open you themselves.
Also, just being the social guy working the venue, chatting up groups of cool guys, then mixed sets with guys and girls, then girl groups -- that will get you much easier opening in general with girls as well. You look like some popular guy, or an authority figure, etc.
