Do I need to use condoms if my boyfriend might have an STI and not know it?

If my partner and I have been monogamous for three years (and I was a virgin before we met) and my partner tested negative for the HIV virus (twice, about two years ago, with a six-month gap between the tests) is it safe for us to use a birth control method other than a condom? That is, are there still any STDs that my partner might have without knowing it, that we should be worried about, even though nothing whatsoever has seemed wrong with either of us for three years and my partner has had several regular annual physicals in that time?


How can I get my girlfriend to swallow?

My girlfriend and I have been dating for a year, and I love her very much. We have a mutually fulfilling sexual relationship, and we communicate well. Recently, I told her of my fantasy of her performing oral sex on me and swallowing my sperm. She said that would be "gross," and has never brought me to climax during oral sex because she does not want me to come in her mouth. I perform oral sex for her, and I enjoy having her sexual fluids on my face and tasting them. We have discussed sexual fantasies before and have pleased each other very much. But she will still not accept my sperm in her mouth, and I feel like she does not want to accept a part of me into her body -- that she does not have the fullest desire to please me. When I first asked her to do it, I expected her to want to pleasure me, to have desire for my penis. Now, I feel like she thinks my body is not desirable. My question is: what must I do or say to make her change her mind, to make her understand how much I wish she'd do this?


Can I use ice cubes to improve oral sex?

I see that in several messages and answers, that reference is made to oral sex accompanied by the use of ice cubes. I'm pretty ignorant about this and would be very grateful to you if you would tell me more about this. My boyfriend and I have a very good sex life and we enjoy making love, but we're also on the look-out for new things to try. I've asked my friends about this and some of them thought it was a joke! Thanks for the help.
