My boyfriend and I have an open relationship. We decided to have one because he is not interested in sex, and I am (very much so, in fact). I love him dearly, as he loves me, but I have so much left to explore about sex and I can't do it with him due to his lack of sex drive. So, I end up having lots of sex with different people, exploring new techniques, and since I've been doing this, I've gotten my boyfriend a lot more interested in sex in general.
