Me (21M) and girlfriend (21F) have had a very good relationship for 2.5 years almost. However, I have issues with sexual intimacy. She is very proactive in that area while I am not very. We are unable to meet so we talk on video chat. She tries dropping me hints for video sex sometimes but I tend to miss it or don't know how to respond because I am not good at sexting in that way and I get awkward. By the time I come up with something or get what she was going for, the moment has passed and she gets mad. This happened various times, including a couple of nights ago while it's her time of the month too so that made it worse. She eventually does accept it and we move on and we are intimate too. But I am afraid of these hiccups building up to something worse.
