Since I also need a life, I will try to answer your questions. A big penis is long and has a wide girth. This easily stimulates the genital tissues around a woman’s vagina no matter how wet she is, so orgasm and sexual satisfaction is induced. Also, a big fat glans can easily stimulate the G-spot which we all know produces bigger and better orgasms. I personally love the feeling of being stretched vaginally and anally. However, there are some definite problems with big penises. Deep throating can prove to be difficult if not impossible. During intercourse, if there isn't enough lubrication, it can be very uncomfortable. If he isn't careful, he can tear the thin vaginal or anal mucosa. Also, if I'm not properly aroused, it can be quite painful to be entered deeply as it feels like my internal organs are being displaced, which they very well might be. A hint to all the well-endowed men out there: The average vagina is only 5-6 inches deep, so make sure your partner is sufficiently aroused before you bang the everloving hell out of her cervix. TY!
