The thought makes my heart drop

The thought of threesomes make my heart drop. I know some people are into that (not judging) but the thought of my husband having sex or doing anything sexual with another female other than me makes me sick. I can’t imagine having sex or involving another woman into our sex life. I think it takes a lot of someone to bring another person into the bedroom.

Anyone else feel this way? Like I said.... I’m not bashing or judging anyone who does do this - but I know I never could do it. I could never share my husband.
