Faithful, yes! What a splendid idea. Summat like this:
'Pregnant ladies, always tie your hair back before vomiting down the toilet. You owe it to your husband to not have carrot-encrusted locks at bed time. How will you ever keep his attention looking like a filthy tramp?'
'Ladies, if you're struggling to feel sensual during the first trimester, try running a cumberland sausage over your breasts to tantalise the nipples and awaken those loins! You should be dripping wet by the time your husband comes home from work' [Disclaimer: sausages are for external use only].
