Anal sex ?!

✨𝑱𝒂𝒔𝒎𝒊𝒏𝒆✨ • LINK IN BIO!🌻

So me and my boyfriend were sexting one day & he mentioned anal sex. I've never had anal but willing to try.. but I've really been thinking long and hard about it. Is there any advice or suggestions anyone can give. I'm just nervous that it will hurt or I'll shit or something lol I just wanna please him & I went along with the sexting but I don't want to be a prude about it either when it comes down to it ...
