me and my boyfriend went for about a year with only having sex every couple of months, if that (I had repeated down-there problems) and our relationship is and was through that time, great! However, sex does help, I got very paranoid he was going to get fed up of waiting but he was lovely, as always! But now we're having sex again I feel a lot more secure, smsagro arent necessary all the time if you're in love with the person although it would be a bit frustrating if you never had one! But maybe if you were just in the relatioship for sex then i would have thought that theyd be necessary! Sorry, very long winded rambling answer there!
