Did I grow? Or no? (Not about dick size)

Me and my girlfriend have had sex countless times in the past, and sometimes(only in doggy style) she would feel my dick poking up near her stomach or abdomen, and she said it's not really painful, just a really weird uncomfortable feeling that's not pain but it is at the same time. It's only when I would go all the way in. But the other day she got back from a 2 day vacation and we had sex and she had that feeling in more than just doggy style. Well. IDK, but the 4 times or so after she's gotten back it has happened. she swears my dick grew, but I just don't agree. It didn't. Well at least I really don't think so. I'm 17, when does a guys penis stop growing? So idk what could be the problem. Is this common for a girl to feel a guys dick up in their abdomen during sex? I plan on being with this girl for a long long time. If this effects our sex lives I'm not going to let it ruin our relationship, but we have a lot of sex, and I am just curious if something could be wrong. Maybe she is pregnant? Would this cause this? But what would explane her feeling the same feeling before hand?

 

Sounds like your penis hit her cervix (where the babies grow), which can be uncomfortable for her. Try different positions.

 

Also, I find that if it's been a few days everything has it's time to tighten up and it feels bigger.

 

It only used to happened sometimes in doggy style. now it happeneds in pretty much any position we try, still.

sarahrei I thought the same thing too at first but we've done it a lot since then and its still the same.

 

Sometime too when I my DH and I haven't seen each other for awhile or we just have been too tired then it feels bigger cause mentally I havent been stimulated.
