All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.
Your talking about sexual matters to arouse each other's sexual desire can have very bad consequences as it might lead you or him to searching for some place to satisfy that desire, hence committing Zina (adultery). So we advise both of you to be patient and occupy yourselves in what pleases Allah.
We advise your husband to do his best to bring you next to him or return home as soon as he can.
Allah knows best.
