Plus size and ttc with Sperm donor

Sooo my story is a little complicated. I’m 310 my doctors say I’m perfectly healthy I’m just fat, but I’m also extremely muscular. I don’t know I’m weird. Anywho my partner and I have recently decided to try for a baby. He is a trans man so yeah you get it. We have a sperm donor who happens to be an ex of mine. He turned out to be a best friend instead of a lover and decided he wanted to help us but with that being said I know that it has to be hard for my partner he can’t get me pregnant himself. I don’t know what to say to make him feel masculine and no matter what he will always be the daddy to our future bean. Back to my weight is there any tips and tricks to help get pregnant faster. I know it takes time and it probably won’t happen first try. I just don’t want it to take forever and my partner feel defeated because I have to sleep with another man every month. (It’s the route we agreed on and discussed still I know it’s hard for him.) I eat healthy, go to the gym, and I stopped drinking and smoking I just need to know if I should do more. I’m going to start tracking my ovulation even though I have a pretty good idea when I do just to make sure. I have also thought about getting preseed. Any help ladies? also big girls drop your baby bumps to give me some more hope!
