Is there any sex scene

No, but due to it's content it is considered to be 'hentai' by some.

Though i really have no idea why... you only get to see like one nipple in all the episodes.
Granted, the women are very busty with bouncing breasts and they don't have a lot of fabric covering their body...
And I do realise that hentai is just a word for 'pervert' which this show definitely is, but hentai is the anime-equivalent for porn and this show doesn't even have that much nudity in it.

It is impossible to find hentai for Golden Boy though :P

Only sex scene I can remember is the girl with the motorscycle masturbating on it.
