Sex is definitely a good idea. If nothing else it keeps your vaginal tissue less rigid since it has to expand a bit for entry lol!
I heard doing the message with olive oil was supposed to work. But im sure having sex wouldn't hurt. Lol dont doctors usally say sex is good to have during pregnacy ? So im sure it can only make it easier.
I didnt have sex my entire pregnancy and i did not massage anything lol but i didnt tear at all:)
I read rubbing almond oil daily around 30 weeks is supposed to help.
