Yes being 6'1+ and buff will get you laid very easily especially (or at least give you the opportunity to take) if you're in uni or in a student environment assuming your face is above average (7/10+). By buff, I mean 160lbs+ of lean body mass at under 15% body fat. I find that girls appreciate male athleticism a lot and sluts in the uni I go to will literally get with guys just because they're in the rugby team, perhaps also because they see these guys as having greater social status. I'm buff myself, and it's quite entertaining going to clubs, seeing the amount of attention I get by both guys and girls (I do think that how I dress also contributes to this aswell). Being 5'10 and under as a guy is a big disadvantage, as it's pretty hard to take these guys seriously and girls subconscious want guys at least 4 inch greater than them. These things don't matter as much as confidence though, which is around 60% of 'the game'. As long as you are 5/10 male with at least 8/10 confidence, you should get about any girls.
