Me and my boyfriend are both 19 and we've got a little girl we've been together for 4 years now and sex was great at first we always had it twice or more a day and now we have it twice a week and sometimes we don't have it for over a week, and when we do he only lasts about 2 minutes and it's the same thing over and over again he only seems to want to do it doggy style. What can I do:(
