<human>: I have been with my boyfriend for 11 months now and things are really great. We get along really well and haven't yet had a major argument, I felt comfortable around him from the very beginning. 

The problem is that we have sex maybe once every fortnight. We both work a lot and spend most nights at the gym, so when we get home we're pretty tired. 

I'm worried that our lack of sex is going to lead to problems further down the track. And to be honest, I would like more sex. I am also pretty shy and scared of rejection, so 9 times out of 10 it's him who initiates it. 

I kind of want advice/tips to help me initiate sex and I guess maybe some reassurance that it's normal...

Can you summarize the given text in a few sentences?
