I feel horrible:(

Samantha • 20 raver or as my friends like to say "dirty hippy"🌵🤘🏼
Everytime my bf and I have sex I fake it. He can get me going but he just can't finish me. I don't know what to do. I love him so much and I don't know how to bring this up to him because he's very sensitive. Are there any ways to fix this problem or am I just screwed?
