TMZ Brunch Bus riders got some dating advice from former ‘Bachelor’ contestant Corinne Olympios … basically, if you’re in love, it doesn’t matter if a dude has trouble getting it up!

Corinne appeared on Season 21 of the hit show — Nick Viall‘s season, which ran in early 2017 … and we talked about the new show he’s hosting, “Age of Attraction,” where couples have to navigate rather wide age gaps.

It shouldn’t matter how much older a person’s soulmate is than they are, Corinne says … because when two people are meant to be, age shouldn’t be a major factor.

That said, any nonagenarians looking to shoot their shot with Corinne will be disappointed … because she tells us she’s taken.

Corinne showed our riders around L.A. — with DJ Teo accompanying her on the turntables — as she shared her raw thoughts. The group stopped at Beaches, where Corinne twerked with dancer Jake the Snake.

The tour bus headed over to Saddle Ranch — home to $9.99 bottomless mimosas –where Corinne went for a ride on the bull … before finishing off the afternoon with St. Felix Hollywood’s famous red slushie margs.

Corinne is also making her much-anticipated return to TV, too. Watch the clip all the way through to hear about it.

Bottom line … Corinne made sure the energy was anything but limp — even though that wouldn’t be the biggest deal for the right tour!
