Re-virginized???

Im almost 33 weeks pregnant. I haven't really had any sexual intercourse my entire pregnancy. I maybe have had sex 3times since finding out i was pregnant. With that being said i am a month away from my due date and sometimes i do find myself really horny. Knowing i can't even attempt sex for 6weeks after pregnancy I wanted to test out the ropes a few times before birth. Me and my SO have tried and failed as the stretching of trying was very uncomfortable and did not work. We've even tried to stretch using fingers but 2 is to many and causes pain. I am litterally only comfortable with 1. This being said i don't know what im supposed to do about this? Foreplay, watching things to arouse me, and attempting to stretch is ineffective. I will go from wet to try almost instantly at the first sign of pain and i dont know how im supposed to work around it unless i just force it and cry about it till it doesnt hurt anymore. What should i do?.?
