lack of desire for sex

We have married 2years.we both had long term relationships previously that didnt work out.my husband only likes to have sex about twice a month and has no desire for it more than that, says he just doesnt need it more. i would like it at least every 3 days.this is extremely difficult for me.we have a very loving relationship and a comitted one.our baby is just under 12months so timing is essential for us.my husband is just not as physical as me.have tried to seduce him by touching etc, he has errections but will not want sex just feels relaxed at that & is enough for him.dont no why this is.please can you offer me some suggestion for help.many thanks.

I do not think you can change your husband. You will have to accept that twice a month is what he can offer you and if you cannot stand that, you will have to find another solution. Would masturbating every third day satisfy you?
