Photometry and first results of extensive CCD-spectroscopy of the UX UMa system RW Sex are presented. The period is found to be P = 0.24486 days and the semi-amplitude of the radial velocity is K1 = 101 km s−1. The mass of a Roche-lobe filling secondary is M2 = (0.54±0.09) Mo and, for M1 ≧ M2, the mass ratio is M1/M2 = 1.5±0.5. The accretion rate is about (2–3) 1017 g/s. The model for RW Sex by Greenstein and Oke is discussed and rejected.
