Lube and ttc

We’ve been trying for 4 months now I think idk I lost count lol. ANYWAYS, i recently read somewhere lube isn’t helpful at all. We use trojan h2o water base- I believe that’s what it’s called. We currently live overseas. He is military so I can’t buy preseed or any that help ttc cause they don’t have it. Nor can I order it because getting mail takes us monthssss to get it’s frustrating!! So I’m asking is the brand we use okay? If not is there anything natural I can do/ use? It’s embarrassing but I can’t really get wet naturally that fast so its difficult… I think it’s because the medication I’m on honestly cause it’s a newer issue. But I read somewhere coconut oil could help, is that safe? I just get panicky because I do get utis easily and my triggers are products. Like if soap gets to close to my area, as well as it took a few brands testing to know the brand we use doesn’t affect me at all.

If you read this far I appreciate you and thanks in advance if you have any suggestions!! Baby dust to us all. 💓✨
