Well, I'll weigh in - what do you want? Just getting laid regularly - it's easier to buy it on the street. Getting a long-term GF? Depends on the lady, but it has been said that "Guys turn on with the eyes, gals turn on with the ears." (Why do you think the French have such a reputation? It's because they're not afraid to be romantic verbally. Oh-la-la!)
Is physique worth something? Yeah, but only with a great personality and a 'let's see if there's something more between us than a hot lay' attitude. I've been hit on by the 'hottest dude around' - what an idiot!
Of course, if you're looking for the mother lode - a faithful, honest, hot, great attitude, fun little broad to MARRY and have kids and grow old together with - personality all the way, baby. After all, get a tough job, get hurt or get sick and all that muscle could do the ol' fat stuff trick - better be something there OTHER than body or she's gonna walk! (and of course, if SHE'S all that, she's looking for the same out of YOU! You got what it takes on the inside?)
We like physical looks, but in a 'wow, nice piece of artwork' way, rather than a 'holy cow, I wanna sleep with that' way. Most of us can admire ladies as well as men - because it is an aesthetic thing. And of course, there are the two schools of women - the one that likes the 'androgynous' dude and the one that likes the 'rough, craggy, manly' dude. Just like taste in art or music, women have taste in preferred 'type'.
There is, finally, (sorry for the book . .) a safety issue. I'm 135lbs soaking wet, with no self-defense training. It is a huge amount safer for me to consider a 160lb guy than a 210lb guy - I might have a chance if he decides he wants more than I've given out. So, moral of the story for big guys? Be the kind of person that 'feels safe' to be around. Doesn't mean you've got to be a pussy, but kind, yes, strong to defend, not strong to destroy.
PS. This is kind of academic for me, since I'm 12 years happily married to my childhood sweetheart, who is also my workout partner and the greatest guy alive! Yes, bod was somewhat important (like, I decided to marry him the first time I saw him with his shirt off . .) but we were ski bums together and dirtbike buddies before the sparks ever flew.
Good replies from the ladies! (You know who you are!)
