Im 20 and have always had bisexual fantasies, been attracted to other women, and generally considered myself bi. But since Ive always gone from one serious relationship to another, ive never had a chance to experiment. My live in SO and I are in a permanant sort of relationship, and i dont think ill ever be single again, but i feel like im really missing out by never experiencing sex with a woman. He's open to the idea of a threesome, but is that possible to do without eventually ruining everything due to jealousy? Perhaps have sex with her and let him watch? He wants to be around b/c hes sort of the jealous type. Comments? suggestions?
