Been in a LDR for 6 months and this is the fourth meet-up in that time. The issue is my boyf is very vocal about when the sex isn't working for him and this time he basically said that what I did didn't even qualify as a blowjob. The thing is he is bigger than average and unlike with previous partners I can't get him in entirely. He says my teeth are also a problem and this visit he basically stopped me mid-point and said it wasn't working. He's also circumcised which I'm not used to. It's left me feeling hurt and embarrassed and I don't really know where to go from here. Are we simply not sexually compatible? Relationship is great otherwise and was moving towards something more settled- plans to live together etc - but this has really made me feel rubbish and like sex is always going to be an issue for us. Feeling pretty fed up right now. Not sure what I'm asking for - advice maybe? Is it possible to move past this or is it the case that sometimes two people just don't physically fit?
