My dh & bf & I have lived together for 10 yrs, with a number of children.
Bf works evenings. Dh works 7-3 usually, with some out of town jobs.
Honestly-we split time as possible, and its rarely alone. With 6 kids who lived with us fulltime, 4 moved out now, and 2 grandsons-me in school full time, guys work full time, kids are home school- almost all of our time is spent with kids.
We try to arrange a date time once a week for each dyad, no kids. But thats not always feasible. Shrug.
Sex is squished in where there is a half an hour here or there, while kids are sleeping or otherwise occupied.
(both guys are straight & we dont do threesomes)
