Gabrielle Union has to ''space out'' her steamy sex sessions with husband Dwayne Wade.

The 45-year-old actress has admitted the Cleveland Cavaliers basketball player's busy schedule can take its toll on her sex life, and during the season the couple - who tied the knot in 2014 - have to plan when they are going to get hot under the bed sheets.

Asked how often she is intimate with her 35-year-old partner on 'Watch What Happens Live with Andy Cohen', the 'Bring It On' star said: ''During the season you've got to space it out between games.''

But when the sportsman gets some time off the pair have more of an ''active time''.

She added: ''Off-season, it's a nice time, it's a good time, it's a very active time.''

And Gabrielle has revealed she is the one who initiates the romps with her lover.

Asked who prompts the steamy moments, she simply said: ''I do.''

Gabrielle has also hinted her beau showers her with raunchy gifts to spice up their sex life.

Asked what the last gift she received from her partner was, she laughed and said: ''That was between games''.

Although Gabrielle - who was previously married to Chris Howard for five years from 2001 to 2006 - has described her marriage as ''yummy, mysterious and honest'', she has admitted she will often ''troubleshoot'' and find faults in her relationship when things are ''very good''.

Asked about her romance and the habit Dwayne is most annoyed by, she said: ''[My relationship] is yummy, mysterious and honest.

''He probably has a top 10. Perhaps I complain, when things are very good I can find where the trouble is, perhaps.

''I troubleshoot when there's nothing to troubleshoot.''
