Is it normal that my boyfriend and i arent haveing as much sex as we used to?

[aja]

we had been having some financial problems for a while. especially the fact that h is not working and i am. it has been affecting our relationship and the roles we,ve taken in the relationship. at the begining we used to have sex a lot. for a couple of months now i had been restricted of touching his penis just because. unless i am planning to have sex. he wants me to be spontenuos, not to plan sex ahead. he doesnt seduce me as often as i would like. must of the time its me who wants to have sex. but i cant just say it. i have to seduce him. when im in my period he wont even touch me. not even my boobs. i miss having that desire burning from his part. i know he eis a very sexual man. cause he used to be. maybe not as often as i would like him too. but more than he is now. the financila problems take a lot of our fights and i dont want to fight over this also. how can i adress this problem? he spends most of his time with me and at school studying architecture. i know he is not cheating or gay. we've been together for a year now. we live together. he used to be married but his ex-wife cheated on him and i worry it may be because he sexually abandoned her..waht can i do?
