butt butt stuff

So my partner is trying to introduce me to buttsex lol, well I was scared and still am but I tried it myself last night (we're in LDR) and well my toy went in smoothly (I used water based lube) and it was good since nothing hurt too much. But, I found out something was bleeding inside and I couldn't cum and I'm a but freaked out with the blood but I'm still willing. Do you girls have any tips or advice? And also I'm still concerned about gross stuff that may happen, how do you deal with that? Thanks 💕
