Please recommend European Female Directors who film hot/intense sex...Thanks:-)

How about Julia Reaves.
She is German. and used to act in Porn in the early 90's. Now she directs, and she has her own label. She seems to specialize in "mature women" Porn, her films can be quite kinky, just like she used to be when she acted.
You can find her entry in EGAFD.

Susi Medusa Gottardi. Try 'Nessun Rimorso'.

I find that, like footballers who turn to management,
female pornstars seldom make good directors [although
to be fair, very few women are given the chance in the
phallocentric world of smut]

I don't know if these count as "hot": Jenny Forte (Italy), Nicky Ranieri (Italy), Ovidie (France), Lisbeth Lyngh?ft (Denmark), Erika Lust (Sweden-Spain).
