I'd suggest that you become a sexual being in your M. Make sure that you are sexually satisfied. Make it clear to H that you are doing so and clear that you would prefer it to be a cooperative project that you be sexually satisfied rather than a solo endeavor. Let H know that a long-term sexless marriage is not in your future.
Treat yourself like a passionate woman, take care of yourself, buy some new lingerie and throw out the granny pants. Be aware of yourself as a woman in social settings. Invest in some decent sex toys.
Quit being an asexual roommate to make your H more comfortable unless you are willing to accept that role as one that you have chosen and embrace.
