Hello all, my gf wants me to cum in her ass, but I'm finding it difficult to maintain an erection after I penetrate. She is really tight back there, and I can't really move in and out easily, and going back and forth just an inch I can't really feel much, other than I feel like I'm going back more than forward. When I push in, I feel quite a bit of resistance, it doesn't hurt me, but I've read that anal with lube hurts her more often than not. She says we don't need lube, but she also says she doesn't like it in there for too long, so I suspect it does hurt her if I stay in too long. All in all, I am greatly aroused by the idea of penetrating her ass, and cumming in there, but I can't figure out how to get enough ease of motion and sensitivity without hurting her. Any advice is appreciated.
