Sex with bigger men

My husband is very tall compared to me. He's 6'1 and I'm 5'4. Before we married we probably had sex less than 5 times and each time it was awkward. We decided to be committed to waiting to have sex for marriage (not be cuz of the awkwardness but more because of our religious reasons) we agreed it was the best thing to do. Months later we married ! 
Now Sex sometimes can be harder than what it has to be and I become frustrated. I'm not used to dealing with a man his height and width. Not only is he tall but he's bigger than the average man. I would say he has a bulkier built, I would compare him to a football players body. Getting on top isn't as pleasurable as I would like it to be because my legs are so wide apart. I feel like I'm getting on a horse lol. And he doesn't like getting on top of me because he feels like he squishing me.... Which he kinda is lol. We tried spooning ... Fail ! The only position we do that is the most comfortable is if he's sitting up on the bed or chair and I ride his lap. And even that sometimes requires a lot of work. We ordered a sex pillow in hopes that it could help with certain angles. Does anyone have advice? Or has ever dealt with this before? Idk what to do it's very discouraging and frustrating.
