G-Spot Stimulation Makes Me Have to Pee

Dear Betty,
I am a twenty-two year old virgin with severe rheumatoid arthritis. I've had a boyfriend now for a year, and though we have engaged in quite a lot of sexual activity, he is afraid that having sex with me will hurt me even more. I have extremely limited mobility in my left hip and right knee, and only so much stamina, but I love him and I want to try it. Even if it affects me poorly afterwards I'm still willing. Do you have any suggestions about what position might be the least likely to cause problems, and perhaps put my boyfriend at ease about hurting me?
Hello Betty,
I am 57, and in the past 2 years was diagnosed with (not severe) rear pelvic wall collapse, and the beginnings of a prolapsed uterus. This discovery was made when I began to have pain during intercourse and problems with constant urinary pressure. At present I am using a vaginal estrogen cream, which has helped significantly with the pressure on my urethra, but I still have pain during intercourse. But my real concern is with my orgasms.
Hello,
I am super embarrassed to even ask this, but ok I am 20 years old and I lost my virginity when I was 16, and I have had 7 partners and still none of them have been able to give me an orgasm, I have had plenty orgasms through the clitoris through masturbation, but never have I been able to reach one during intercourse through my g spot. I think I am just scared and do not let it happen, but I am sooo sexually frustrated.
Dear Dr. Betty,
Dr. Betty,
I have a kind of unusual question, and after seeing you on television, I figured you may be one of the best and knowledgeable people to ask. My ex-husband and I have a fairly good sex life. I think he is not as freaky as he claims to be. His idea of freaky is a threesome (with him running the show). But, since I'm not into it, we have not tried it. His hard-on seems to increase when he mentions me with another man. He frequently asks me about the size of my past lover's penis'.
Hi there Gorgeous Betty,
Dear Dr. Betty,
I love your advice in Bust, and felt like you were the safest and most reliable person to ask this question (and was afraid what I would get if I "googled this!). I've been with my boyfriend for 4 months and it has been the most loving and sexual relationship I've ever had. The last time we had sex, he was giving me oral and started to lick my anus. It felt amazing and I had a great orgasm.
