What do guys like???

Good question; the thing is that women are more emotional than men, so I think women require more care in that area; for example, my girlfriend loves it when she gets flowers; if she were to get flowers for me, I wouldn't really care much cause they don't have an impact on me; of course, that's a silly example as most men don't care much for flowers, but my point is that women need these type of thoughtful gestures more than men do, if they ever need them at all.
Now, one thing I really enjoyed from one girlfriend I had was whenever she gave me surprise rapes; and by that I mean that most of the times, it was me the one initiating for sex, but once, I was just resting and she came out of nowhere dressed in a simple bikini, and then she just went on to seduce me; I was really amused by that. Also, you need to learn and see what is it that your boyfriend enjoys; when I used to live with one of my exes, I liked it when she gave me time to be on my own and do my thing like read the news, read a book etc; some women are clingy and they don't give you that alone time.....so the best things you can give are those acts/things that your boyfriend would appreciate, so that's why you need to pay attention to what he likes. OH yea, is there a special food he likes, or maybe music that he enjoys? You can always take him to a restaurant that has his favorite food, or a place where they play his music, etc...

Oral sex and steak. A timeless classic. Light up the grill and go down on his meat. You can never lose with that kind of service. This is a great way to show your man you appreciate the little things he does for you.

I do believe that was my shortest answer ever... such an easy question, though.

Guys like surprises as much as their girls do. If you got him something relating to his interests how can he not like it. I find that a nice box of chocolates is good for me, and even tickets to a show or a concert is something good also. My girl recently bought us tickets to a theme park that we are going to this week.

What are some of his interests maybe I can help with some ideas.

Something personal? something that has meaning to the both of you=)
i don't know what sort of guy your boyfriend is...
but it's always nice to give him something that has meaning only between you two.
however random it is=)
like I call my boyfriend my teddy and hence got him a teddy bear on my way back from holland
he really liked it and won't sleep without it and has it by his computer at all other times xD
asI said I don't know how cheesy your guy is tho=)
and moving on to the no matter how random ur gift is...
i have a white dog and whenever he comes over he insist on wearing black and gets my dogs fur all over his shirts, ants, etc. When I asked him why he said "because I look sexy in black!" =P So for valentines day (i know very random but I didn't have much time at all) I got him one of those sticky pet hair remover things and wrote up a card saying "Because you DO look sexy in black... x" he said it was the cutest gift he ever received and even though we kept the roll at my place he keeps the note in his wallet=)
just random things I know but my point is, something that has meaning for the both of you=)
