bit of a factor

[Pavel Pin]

Eggsy asks his lover Tilda's permission for to sleep with another girl as part of the mission:

Eggsy: Right. Well, I mean... I want to be with you, but being a public figure, babe... like a prince...It's a bit of a factor, you know, what with my job and stuff.

He means that sleeping with other girls is part of what a public figure requires. It is a 'factor' in his reputation -- one of the things that makes him seem glamorous and interesting.

It's this meaning of factor:

1. one of the elements contributing to a particular result or situation: Poverty is only one of the factors in crime.​

The use clear, but it is odd to use such businesslike language in this context, when he is talking to his girlfriend about sleeping with someone else.
