Sevyn Streeter & B.o.B on break...& friend claims it's because the singer wants more sex than the rapper

R&B singer Sevyn Streeter and her boyfriend rapper B.o.B are currently taking a break from their relationship and according to a friend of the couple, it's because they are not s3..xually compatible as Sevyn wants way more s3..x than B.o.B. He's hung like that and doesn't have a huge s3..xual appetite?
"Sevyn and B.o.B. really love each other. They have chemistry, everything, The only problem is the s3..x. Sevyn has a real strong s3..xual appetite, and she needs a lot of it. B.o.B is more laid back and doesn't crave it as much. I think that's what cause them to split." the anonymous friend supposedly told MTO
