i’m confused about something I’m really worried because I am a married women I have kids I was bicurious. so I explored with a woman my husband let me try it out everything was fine but mid morning my husband and I had sex which is totally normal. But then that same day in the after I went to go meet the girl that I have had weeks speaking to and she only sleeps with women so her period is late by 3 days she took a test I think a day or two again and it’s negative. But I’m wondering should she have gotten pregnant by rubbing out vaginas together (because I had my husband sperm inside me) I have been so worried today I’m going to take her First responde test and see what happens. This isn’t a troll post or fake post it’s something real and I’m just very nervous because I never had sex with a female before and idk how these type of things work so please no shaming, I’m just asking something.
