Just to add what I think:
I've been in a relationship for 2 years now and I think our sexual life is killing the relationship. Sometimes I'm not in the mood (have my own problem ) the other time she doesn't like it... and we are starting to grow apart

I do think sex is important. But it depends on you and your partner.

You just made me think and I will try to fix my problem and try harder for her...
Thanks
