Jim Carrey says "every day is Valentine's Day" with girlfriend Jenny McCarthy.

The 'Yes Man' actor feels more comfortable in his four-year relationship with the former Playboy model than in any other romance he's ever had.

Referring to the upcoming romantic day (14.02.10), Jim - who is twice divorced - said: "Jenny is the first person that I've been with where I don't have a giant question mark over my head. Every day is Valentine's Day, baby."

Jim, 48, believes honesty and good communication are the key factors in their happy union.

He added: "Say what you mean. No one has the energy for mind games."

But for Jenny, 37, the special thing about the actor is he makes her feel sexy.

She listed her relationship tips as "communication, being turned on by each other and being each other's soul mate".

Jim added to People magazine: "When you're not turned on, there's generally something to talk about. So, it's good to listen to that."

Jenny also loves the fact Jim has developed a close bond with her seven-year-old son, Evan, who was diagnosed with autism in 2004.

She said: "I think a man who is good with children is sexy. And Jim definitely is. He loves Evan so much."

The couple were speaking at a poker tournament they were hosting to raise funds for their autism organisation Generation Rescue in Miami, Florida.
