What are some tasks that are safe to do while pregnant?
Dificult question, mmm the thing is most of the pain you suffer the baby will feel it so, it must be something you really like as a good sensation, clit rub anal insertion, also if you want to use any sex toy you must have extra hygiene many troubles in pregnancy comes related to vaginal infection, also depending on the weeks of preganncy you can´t have many positions for short period of time, nipple play can be a problem too so as you can se you are not playing for one but you must watch the baby too, even so you still can play.
use some oil in your body massage oil is a good one but cacao is perfect, you can use this to rub your breast wile playing with your toy, anal insertion is acceptable, some psychological punishment can be done too but once more it need to be not too hard, some humiliation some role play but nothing that generate stress.
my recomendation, semi public, anal insertion, clit punishment, body writing, mild humiliation, some denial,
forbidenn.- ropes, blader control, vaginal insertion(long period of time) nipple punishment, in fact any mild hard pain punishments, and any MEDICAL contradiction that pregnancie has as self medication drink smoke raw fish etc
Hope this help you if you have any trouble ask your doctor.
