Am I crazy? 🙁

Mary
So me and my boyfriend are long distance so we have our sexy time over Skype. I'm a very shy nervous girl but eventually I worked up just enough courage to video call instead of voice call during that, I did it twice and both times I was very uncomfortable. (keep in mind we call every sat-mon sexy time or not we always call) so the next time he asked of we could video call I said not this time it still kinda makes me uncomfortable and he said OK goodnight I'm tired. Then he asked the next weekend if we could video again and I said no again.... Again he said I'm tired we should sleep I said oh OK. Bout ten minutes later he said we could call he didn't want me to think he was mad and I said no go to bed..... What do you think this means 😔 I love him we've been together 6 months and he's my first love what do I do 😢 is he just in it for the sex this only happened this weekend and last weekend.... What's going on here 😢
