Help me lactate

[Smoothie]

Besides nipple stimulation, I understand sex while laying on my side will help.
Any tips?
Should I used a pump and toys?
Should my bf be more rough or more gentle? What will stimulate lactating?
Am I just supposed to lay on my side and toy myself?


I'm confused because people have told me endurance is best. So I should ask my boyfriend to extremely often?
If I'm to lay on my side I should toy as long as possible no matter how sore?

Will being turned on help, or is it all about extensive nipple and anal stimulation on my side?
