ADHD and sex?

My boyfriend has ADHD and we are are in a long distance relationship(im his only one so dont even go there).Anyway we cant have sex so we master together.Im always in the mood he rarely is.Soemtimes though he starts talking dirty and what not and then completly changes the subject and if i try to go back to it he says nevermind.Also when we are doing it he sometimes talks about random stuff that has nothing to do with it (example one time he said ive never mastered in these pants before).So with all that info my real question is is this just his ADHD or is it something else becuase i dont think a normal guy would act this way(oh hes not on any medication for it but he used to take ridelin for like 10 years ).Any ideas will be appreciated.

I dont have a problem with it i just wish there was more i could do for him.I dont know if he enjoys it as much becuase of this.

Sounds like ADHD...people have a hard time holding thoughts when they have it so when they think of something they say it at the moment the thought comes into their head...whether during sex, like you are all into it and then he says "oh I seen Jay at the mall today, he said to tell you hey", or during a movie that you are really into he says "guess what happened to the cat today", not sure why this happens exactly but this is what i have found with friends, family, and self...so I hope this helps you.

It could be becouse of he took the meds. for so long . I know how he fells becouse I have ADHD
