Ughhh idk what to do

Soo my husband and I have been told for about 8 years now we got married (civil court) like 6 years ago and we got married (church wedding) just last year. Well at first sex was literally every day. (Even twice a day) but now the years have passed we now have two kids (toddlers) we have sex maybe twice a week. I haven’t been feeling pleased lately I feel like sometimes when it does happen I wanna get pleases but he always wants to only from the back. So I please him. I have been getting annoying I haven’t told him anything. I just feel like just how you please you’re man he needs to understand he needs to please me here and there too as his wife. And I’m not getting it. Soooo many crazy ideas get into my head that are not good and by that I’m mean like wanting someone else to please me. As awful as it sounds I haven’t done anything like that ever. There’s just things that come into my head that I know I shouldn’t. But I just feel like my own husband doesn’t full/satisfied me in pleasure he doesn’t even try . And idk what to do 😣
