It’s quite simple, really: Scottish men make it so easy to get busy!

That’s according to Caitriona Balfe, who was asked by Stephen Colbert on Thursday’s installment of The Late Show to explain why the sex is so good on Outlander. The actress who plays Claire Randall Fraser had a winning reply, as seen in the clip above, along with another explanation for why her alter-ego is so good in the sack.

Balfe stopped by the CBS late-night show as part of a big media campaign in New York City this week to prepare for this weekend’s return of Outlander on Starz. She and costar Sam Heughan (Jamie Fraser) made appearances on The View and Live with Kelly and Ryan after participating in EW’s subscriber-only event on Tuesday. For highlights, click here.

The Late Show airs weeknights at 11:35 p.m. ET on CBS. Outlander returns this Sunday at 8 p.m. ET on Starz.
