Nudes vs Revealing Pics. Insecure.

I’ve been in a relationship for nearly 4 years now. The idea of sending nudes kinda freaks me out bc I’m not comfortable in my body but I do send pics to my bf sometimes in revealing clothing. Usually I’ll wear high waisted shorts or leggings or jeans in the pic. Is that weird that after 4 years I don’t send him pics? We have sex like 1-3 times a week depending on how many times we get a chance lol but bc we don’t live together I haven’t seen him in weeks. He used to ask me for them but then I’d get upset while taking them bc I hate my body so much and I told him that and it’s been a year since that and he hasn’t asked me again about sending pics. But sometimes I feel ok to send the pics. I sent some today and it felt good. I put on make up earlier in the day (for fun, not for the pics) and my boobs look fuller today (thanks hormones) and i hadn’t eaten lunch yet so I looked kinda thinner. That’s the only way I’m able to send them... he LOVED them a lot lol. He never pressures me into the pics, today it was my idea bc well its been 3 weeks now since we’ve physically been together and so I thought I’d give him a treat and it ended up making me feel good too. I usually feel insecure bc he’s had problems of being distracted by girls in the past and usually girls that look nothing like me too. I’m worried that since he doesn’t get pics of me he is looking at other girls and maybe because I don’t Iike sending them, he is more likely to look at other girls?? I know that even if he notices other girls it doesn’t mean he doesn’t love me but I feel so insecure even though objectively I know I don’t have a bad body! I have a little chubbiness around my stomach and pretty small boobs so I feel insecure but I eat healthy and I’m 5’4 and 125lb ish. The only thing I like about myself are my legs and even then usually just in jeans or leggings, sometimes shorts. People always tell me I have nice legs whenever I wear shorts but I don’t see it how they do.

Idk why I’m posting this, maybe bc I wanna vent my feelings? Maybe I’m wondering if I’m being stupid for feeling insecure when he tells me I’m beautiful all the time. Idk. Thank you for reading if you did and I’d appreciate any sort of replies :)
