I'm comfortable only when there's a mutual attraction. That's what anyone wants. If I find out she's not attracted to me it brings down my level of attraction to her. If I'm interested and find out she's not I tend to cool off.
Start with a clean grill. Keep it clean by brushing with a wire brush after preheating and again after cooking. Make sure to oil your grates and your food before putting it on the grill to keep it from sticking.
