Painful sex

Any of you ladies experiencing painful sex? I'm 36 weeks pregnant and ever since I hit my third trimester I haven't been having any sex with my boyfriend lately but occasionally when we try it hurts everytime so bad I can't bare it ... It doesn't feel good at all my insides are sore and irritated afterwards. it's like my insides are sensitive or something and it's so painful I hate it. Anyone else experiencing this or has ?
