Sexless marriage!! Feeling desparate

Hey fellas! Honestly it took alot of guts to.post this out here but I'm in a sexless marriage like my husband has sex once in 2 months . Now im pregnant so no sex at all. Im 30yrs old nd he is 36 . I feel its just not.our age to just think about kids and be together for their sake. When i tried discussing with my husband he said he has errection issues . I dont know if thats true or if he is just bored from me . I feel so desperate for sex that i have started watching porn to help me feel better. I need some suggestionsas to what should i do. I cannot live a sexless life .
