Romance content rating scale

When I say that my romances are cozy, sweet, mild, or no/low heat, here is exactly what I mean...

1. No heat, focusing on emotional connection with no kissing.
2. Low heat with a focus on emotional connection, holding hands, light kissing.
3. Moderate heat romantic content with heavier kissing.
4. I haven't written more than 3, but 4 would start to include backstage or off-screen sexual content implied, etc.
