We've went from threesomes to almost nothing in a matter of 3 years. Outside of sex, our is good in my opinion. I'm a thoughtful and caring boyfriend. I've always put her first. Communication could be better, but I've always asked her, are we good, did you want to talk about anything? Etc. I've even set up a couple of sessions with a sex therapist. Still it's like pulling teeth for her to engage in sex. During our last session in March, now she says she doesn't like oral sex anymore. LIKE WHAT THE FUCK?!?
