Absolutely. For some people, sexual attraction is undeniably connected to love and one is impossible without the other. For others, sexual and emotional attraction are completely different. Preferences, when it comes to sexuality, are not always in sync with romantic preferences. In this context, it is possible to have a physical or sexual attraction towards one gender and an emotional attraction towards another. It is why sometimes we can make a difference between sexual orientation and romantic orientation (see question about sexual and romantic orientation)
