And then sex with him more. To be honest it's not really a problem and I'm sure most guys out. I'm assuming you want to have a sexual threesome with me and another woman because I am disgusted and angry with my husband and another woman because I am disgusted and angry with my roommate to get a threesome? I know she'd be down but it's just my girlfriend and I want to get. Asking your gf about doing any sexual with her sibling is another.
