Dear /r/relationship,

My gf (27) and I (30) have been dating for about 7 months now. This relationship has been the best 7 months of my life, we are both madly in love, spend almost all of our free time together and can't get enough of each other. We've already made plans to move in together and already discuss marriage and children together in full confidence that this is where we are going.

However for maybe a month or 2 now, sexually we've entered in what I can only describe as a routine. We've both been in our fare share of relationships long and short so we're both aware that this would come sooner or later. We've discussed this with each other and have talked about ways to spice things up but haven't gotten around to try them out yet.

Since last week though things have gotten a little worse, my gf has basically gotten to the point where she has no sex drive any more. This is clearly upsetting her (and I as well). When we first started dating we would go at it 2-3 times a night to the point were our bodies were rejecting the notion of another round. Now we are down to 2 times a week at best. 

I'm not too sure where I'm going with this but I feel the need to discuss this with other people. My mind is going crazy with what could be happening, I'm scared that I may not be attractive to her any more, I'm scared that there might be something she is not telling me. I'm scared that I don't please her any more. I don't know what to do, I don't know how I can help but I don't want to just wait until this collapses... Is running into this problem normal at this point? Has anyone else been in this situation and what have you done to get out of it? 

The simple thought of losing her keeps me up at night and I can't concentrate at work because I can't stop thinking about this. Any advice will be appreciated.
<bot>: We're at 7 months and gf has lost her sex drive. Is it me? Is it her? What can I do?
