My man and I have recently started having sex (the first time for me.) We have done it about 4 times now and while sex with him is fun, often times I can't take his penis. It's long and kinda wide and when he puts it in I make an audible gasp. Sometimes he'll get on top or behind and stroke for about a minute or two and I just have to tell him to pull out (and he does.) Or sometimes I ride him and it just takes the life out of me! Lol. And after he ejaculates, he also wants to go more rounds which I can't do sometimes because I'm just lifeless (not literally.) I was wondering was there something wrong? Is there something I can do to be able to maybe ease the pain and last longer?
Also, sometimes I don't orgasm... Any ideas as to why that might be?
