Too big is a matter of opinion and nothing more. In my world saying that you're too big is a lot like saying that you're "too rich" or your getting laid "too much". However, I'll be the 1st to admit that there are a number of reasons girls did Nick Lachey's body over my cretinous 300 lb physique.
1. What 115lb girl really wants a 300lb guy on top of them sweating during sex? Unless they've fucked a big guy before that was capable of supporting his own weight during sex without having a heart attack, she's probably going to be scared you'll snap her pelvic girdle. Justin Timberlake doesn't have have to worry about this image running through women's heads. Howver if I were gay, he might have to worry about his own man-gina getting punished just like bitches do. lol
2. Big guys are man whores that get pussy thrown at them 24/7. This is a myth. I've been big since I was 14 yrs old. I got an above avg number of notches on my bedpost, but nowhere near some of the guys I know w/ boy band bodies. Anyway, chicks don't want a guy that they think is getting propositioned by horny sluts wherever they go. After all, a guy is only as faithful as his options. For most girls, dating a BB is like a guy dating a stripper or cocktail waitress. Why on earth would you wanna get emotionally attached to a chick that basaically gets hit on everyday for a living??? So why would a girl wanna seriously date a BB that (she thinks) gets hit on constantly???
3. The "S" issue. Steroids are illegal and the misinformed general public hates steroid users-often labeling them as druggies or cheaters. So don't expect a girl's often jealous friends to be supportive of on your relationship from day one. Don't forget the whole roid rage thing either. Guys that use their roid use as an excuse to be an asshole to everyone make this myth appear to be true.
4. The lifestyle-If you're eating/ training/sleeping how you're supposed to-while working a ft job, you probably won't have enough time in the day to hang out w/ a girl to keep her happy. She'll usually be ok with your lifestyle at first, but after a few weeks she'll start depriving you of sex in an effort to get you to spend more time together. A lot of guys give in to this. 6 months later they're 25 lbs lighter and feel like shit about how they look. This is the perfect time for her to dump you. She took your nuts away by limiting sex, now you feel less attractive and more vulnerable. So when she does dump you it results in you making an even bigger ass of yourself by crying, begging, stalking, etc.
5. One thing is fersure-if you're big and know how to fight being a bouncer at a club is the best job you can have for getting laid purposes. Alcohol lowers a lot of girls inhibitions so they'll hit on a bouncer/big guy even if they never would when they're straight. I used to go out to my shitbox car after the bar closed and I'd have 2-3 different chicks waiting around for me to fuck them. The best part? Other guys spent their $$$ on these chicks all night long hoping to get a piece-and I didn't have to spend a dime on them.
