sex positions in the 3rd trimester

which one works best for you? I've mentally given up on sex but try to engage sometimes because it's not fair to hubby lol. today he asked if we could try different positions to make me more comfortable 😂 i felt so bad. we've only tried missionary. I don't have the balance or energy to be on top at 8 1/2 months pregnant. what works for you? i feel like a whale no matter what but i need to figure something out to make sex more appealing to me
