We want different things sexually but analyze: can this work? Map sexual compatibility: frequency mismatch vs. acts mismatch vs. values mismatch. Calculate: my needs vs. their needs vs. compromise possibility. Show me the sexual incompatibility: these differences are workable, these aren't. Give me the reality: this is bridgeable gap, this is fundamental incompatibility. Include: whether sexual incompatibility will breed resentment, what's negotiable, and if we're sexually incompatible long-term.
