Sex and Prozac

We have been together for 2 years. We were in an LDR up until 3 months ago. We are now living together. Over the summer I went to see a therapist and was prescribed prozac. I feel that the prozac is helping me, but it has really put a damper on my libido. DF and I discussed the possibility of me having a low sex drive, if any, prior to making the commitment to go on prozac. I am extremely busy in an graduate program. Many of the nights I come home exhausted. We have been having sex about once or twice a week. But in between those days he dry humps me a lot, much to my resistance. :( I have also experienced sexual assault, and have feelings of panic when he will joke around and play about. There are times when he will beg...and I feel awful, but I also don't feel up to it. When we do make love, it is wonderful, but I also prep myself with thoughts of the act and get in the mood to help offset the lack of libido with the meds. We don't have set days or anything, there are times when we will have great sex 3 -4 times a week.

I have talked to him about it, at the moment it has happened, and I have also sat him down to talk about it. I have asked him to "romance" me more if he wants to have sex rather than dry hump me. What else can I do? Should I just let him get off on me? Or in me? I would prefer to be in the mood during the act and I'm nervous that just letting him get off; I will start to resent him :confused:

Please help.
