French people in general appreciate it when an expat makes an effort to speak at least a little French. Funnily enough after a few sentences of broken French, the French usually slip into English. Even if your French is better than their English. But… you need to make that token effort to kick things off.
As far as Frenchmen are concerned, they think French spoken with an accent is exotic. As an anglo, you’re already different from French women, and if presented right this can be refreshing to a Frenchman, so much so that your accent will be the icing on the cake. So practise that French! If you play your cards right you’ll also be practising your French kissing. And for that I’m pretty sure you don’t need any tips.
If ever your French is a bit rusty or non-existent, think about taking some classes or joining a conversation group. Remember, a bit of French will take you a long way. Not only to attract a Frenchman, but also to fit in with the locals.
