Need advice..

For the past few months I've been struggling with staying wet enough when having sex and since we started ttc (since June) my hubs has been taking longer to 'get there'. I just get so dry dry and it mainly is painful near the opening I feel like my outer skin is being pulled and it starts to chafe and burn.. We've tried lube but it only helps a little. We really don't even have that much sex.. We try everyother day while I'm ovulating and other than that it's like once or twice a week. Since we are ttc I don't always take the time off from doing the deed to let it recover a bit down there. I'm just so frustrated.. Any advice or just knowing I'm not the only one dealing with this crap would be appreciated!
