Well, if you express several different things you're looking for (e.g. good communication, personal values, affection, goals in life, and ALSO great sex), you don't look like only wanting sex. :-)

OTOH, if you mention how important sex is for you - among other things - and she says "You're only interested in sex!", it's likely she has issues on that matter and isn't sexually open. Better know that sooner that later! ;-D
