Kristen Stewart reportedly has intimacy "issues" with her boyfriend Robert Pattinson.

The couple are thought to have reconciled recently following Kristen's affair with married director Rupert Sanders.

According to the American edition of OK! magazine, Kristen doesn't feel sexually satisfied with Robert.

She desires for them to visit a sex therapist to address their problems.

"She loves Rob and can't live without him, but that doesn't mean that there aren't any issues," a source told the publication.

"They were having a major disconnect in the bedroom when she cheated on him [with Rupert] and that hasn't been fixed."

Apparently the couple's coitus problems have only increased since reuniting.

Robert is finding it tough to forget about Kristen's adultery.

"If anything, it's worse, because Rob is still so angry at her," the insider said.

"He wants to be with her, but he hasn't totally forgiven her, which is making it difficult for them to connect."
