1 year and 4 months w/out sex

So my boyfriend and I have been together for 2 and a half years, but we haven’t had sex for over a year. We talk about it a lot but we just never do it. We had a more serious conversation about it today and he said that he just feels too chunky to have sex, even though he’s 5’11 and weights 200lbs. Since we’ve been together I’ve gained 80lbs. I’ve been working on losing weight for a while and I’ve lost 20 lbs so far. He decided that’s he’s going to start working out with me, but I can’t help but think that he thinks I’m too chunky to have sex...
