keep the conversation sexual?? that seems like a bad idea... are you sure they didn't mean to keep your sexuality alive and present in the conversation? that makes more sense....
I always have a sexual vibe, but above all else I usually have a respectful vibe as well. So i'm never going to walk about to a girl a strike up a conversation on her favirote position, or if she likes her ***** ate.
Remember, Keep yourself sexual, sexy, mature... a man! But I dont think literally keeping the convo sexual is the way to go.
can you post some references of where you have been reading this anyhow?
